The instrument used was a euvette with plaxe-parallel walls, filled with 11.4uid He uraer atmoa- pheric pressure. An interference pattern(fringexs of equal thickness), which is a function of the distribution of densitywas observed. Heat was pro- duced in a heater, and passed through the He in the cuvette and then through a platinum foil into the surrounding helium bath. When enough heat was liber- at:%d, a stable visible boundary was produced between He I and He II (photo- grLphs are givert), indicating a jump in density at the boundary. An inves- tigation of the variation in the interference pattern with variations of the heat flow w led to a determination of the variation of Af (w), which turned out to be juadratic.

Devices for obtaining He3: The first device consisted of a DEWAR vessel with liquid helium (2,30K), from which the He3 is obtained. It permits enrichment up to 0'p2%p i.e. by the 105-fold, which is, however, not enough. Besides, the device does not work continuously. With another device which w9rks continuously, the helium'is introduced under atmospheric pressure. The He9 was led off through a filter in form of a superliquid flow forelhe purpose of euriohtment by thermo- osemosis. Besides, the gas enriched by H was led off by means of rectification on the tube. The helium is in an exterior DEWAR vessel under atmospheric pressure and is, according to necessity, replenished from a liquifier. The device is de- scribed in detail on the basis of a drawing. In0-the interior of the DEWAR vessel temperature was kept on a level of from 1,9 - 2 K. The He3 was completely re- moved within the limits of error, and the enrichment coefficient may be put at 2.104. PMHKOV, V.P.;KA(;HINNKlY.

In continuation of a preliminary investigation carried out by the author (Ref 1) of the same problem, the present paper describes experiments carried out for the Purpose of investigating the density- and temperature continuity on the boundary between super- fluid and, nonsuperfluid helium in the presence of a heat flow. The device, -which permitted optical inveatiga-tion of the phase boindary is reprettented by figure I and i4 described in. detail in the intro- duction. Figure 2 shows a total Of 16 photographa of strips of equal optical thickness such as were observed in the courie of ex- periments. The first four were taken with the camera inclined at 70 towards one side, and the further 4 photographs were taken with the camera inclined at an angle Of 70towards the other side. The Card 1,1% last sexies ubows these strios for an inclination of 4.5o. 2- 30V/56-35-~-4/44 Observation of a k-Transition in Helium for a Beat Flow Through a Phase Boan~ary The horizontal rows of the photographs correspond to heat flows of 0, 0.06, 0.11, and 0.19 WICM2. The results obtained by mea3Uring density- tand temperature continuities are shown by figure 3 in form of a diagram. Density jumps are proportional to the square of heat flow density and at 0.16 W/cm2, for instance, the density of of nonsuperfluid helium on the boundary io less by 1.3.10-34Vcm3 than that, of superfluid helium, i.e. by about I %. in superfluid helium a temperature gradient of dT/dx - 1.5-10- 3degreea/cm Was 2 observed at W - O.Ob W/CM . In nonsuperfluid helium (with W being equal) a temperature gradient of 10 degrees/em was found. In con- clusion, the author explains boundary stability and gives several examples of a disturbance of this stability, which may occur in the case of high thermal flow densities. The author finally thanks P.L. Kapitsa, Academician, for the interest he displayed, and he expresses his gratidtude to A.I. Filimonov and I.A. Uryutov for helping to carry out the experiments.-There are 5 figures and 3 Soviet references. Card 2 2SW "Mon Cheat---. 1. !tj.t.. of L.. Th. ftfsh P. .1.11kh PE310DIC&L. C.q.kb& ...k. 1)5~.

All measurements were carried out by means of visual observation' * The device with which the authors operated is described in detail; its inner part, which consists essentially of a double-walled Dewar vessel, is shown by figure 1. A Dewar vessel with liquid He4 contains a transparent Dewar vessel with liquid He3; the latter contains a glass ampoule, into which a condensed He3_He4 mixture is introduced from above through a long steel Card 1/3- capillary tube. The temperature of the mixture In the glass I Phase Diagram of Liquil He,-He4 Solutions .Card 2/311 SOV/56-37-1-5/64 ampoule is measured by means of a resistance thermomete4 and vapor pressure by means of a MacLeod manometer.

The data obtained by the authors, those obtained by Yesellson, Bereznyak, Kaganov (Ref 4), as well as those obtained from reference 7, are located on continuous curves; the curve of reference 3 partly shows a certain deviation.

It was found that a turbulence front moves with constant velocity v T ' 2,2 '_ 0.1 mm/sec from the heated end to the cold end of the tube. This front increases the thermal resistance of the helium. On the other hand, a front with the constant velocity v. . I *_ 0.0.5 mm/sec propagates from the cold end of the tube.

Pretreatment of the helium has a consider- able effect upon the turbulence. Turbulence occurs at the ends of the capillary tube but may arise also inside the tube at a subcritical heat flux if the settling time of the helium before the application of the heat flux was too short.

TITLE: The reagon for the loss of the superfluid properties PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, v, 41, no. 501), 1961, 1443-1448 TEXTs In order to investigate as to what is the reason why helium II loses its superfluid properties, the authors measured the critical velocities for the superfluid part and for the oppositely moving superfluid and normal parts with the apparatus shown in Fig. 1. The authors had adopted W~ F, Vinen's method of second-oound attenuation (Proc. Roy. Soc., A240,128, 1957)~ The capillary tube in which the flow was measured had a diameter of 0.385 , 0.005 cm and was io cm long. The counter-flow was established by a heater. The single superfiuid flow was raised by the thermodynamic effect through the Fe2 03crocus by another heater, The capillary tube and its lower lid together formed the second-sound resonator with a Q of about 140.

The critical velocities of a single superfluid flow., caused by the heater 4, and of the counterflow, caused by heater 2 were determined from the attenuation of second sound in the turbulent flow. The measurements definitely showed that the velocity relatively to the walls must be considered the critical velocity. A value of about 0.03 cm/sec was found for the latter, The loss of the superfluid properties is due to vortex rings arising at the walls of the capillary tube, P. L.

It is shown that at temperatures on the order of several millidegrees the cooling effect is proportional to the heat of transition q = 100 T2 [J/mole]. The apparatus will produce a temperature of 0.001K and a beat absorption of 5 erg/min at this temperature, at a HO circulation rate equal to 1.6 x 10-4 mole/see.
