Measurement of the ffard Fraction of the Neutron Spectrum 501'/89-6-5-17/33
In the Reactor BR-5 by Means of a He3-Ionization Chamber
and therefore washing out duo to helium rebound in the
chamber-may be neglected. During measurement of the active
zone the helium rebound in the momentum spectrum is, how-
everg distinctly marked. It wasq for the time being, taken
into account only on the basis of theoretical oal.:ulations
-and will be- experimentally checked -after all work connected
with putting the BR-5 into operation will ha:ve been com-
pleted. There are 1 figuro at%d 7 reforenociii, I of which Is

Abstract The Bartree self-consistent fie3AL method, extended to in-
clude the case of the two-configuration approximatiov, is
applied-to the lowest conkigurations of the carbon atom.
The-Hartree eqmtione, eupplemented by configuration
-terms, are solved-for the 2p-radial wave functionsvIkich
are taken into account by the coafigurationso and the va-
lues of the total energy are given* In this approxUation,
the authors determine the effect of the mss of the tspec-
tral lines, arising from transitions between the Investi-
