They.have been able to separate indium from large amounts of antimony and tin by means of extracting tin (IV) and antimony (M) from a 10 N R solution. They 2SO4 studied also the extraction of antimony sulfate from concentrated H2SO4 solution with use of chloroform. There are 2 figures.and 2 tables.

TITLE: Fast-proton induced fission of antimony nuclei PERIODICALt Doklady Akademii nauk SSSR, v. 137, no- 4, 1961, 826-829 TEXTs The difficulties in the experiments described here mainly consisted in that the fission fragments of antimony nuclei possess very small yields as compared with those of the disintegration products. lo-3 % of impurities lead to strong deviations from the correct results. High-purity targets had therefore to be used. The targets were irradiated in the synchro- cyclotron of the Ob"yedinennyy institut yadernykh issledovaniy (Joint Institute of Nuclear Research) with 660 Mev protons; the products were chemically separated:(Z = 11 -37). Great difficulties occurred here too, since antimony fission products are often identical with antimony disinte- gration products. The isotope production cross sectionswere calculated by conventional methods. The results are compiled in Table 1. As-can be seen from the diagram in Fig. 1, the fission of Sb takes place in a much Card 1/7 2248.9 S/020/61/137/004/013/031 Fast-proton induced fission of... B104/B206 wider interval of theratio n/p as is the case for heavy nuclei, With itp however, the share of neutron-deficient nuclei is also greater than for- heavy nuclei. Most of the nuclei identified by the authors are "protected" (z ashchishchennyy) isobars, which makes it possible to determine the little known distribution of the nuclear charge on the fission of Sb. The distribution of the isobaric output is shown in Fig. 2.~ The half-widths of the curves for the individual isobars are 3-4 unit charges, while the same half-widths amount to 2-3 unit charges for the fission of heavy nuclei. The line which connects the most probable nuclear charges of the fragments lies close to the line of nuclear stability. The fact is also mentioned that the Sb fission takes place symmetrically (Fig. 2), which is similar to~ the fission of Ag. With A reduction of the proton energies to 220 Mev, the portion of asymmetric fission products is reduced. As it turned out, the fission of,Sb is accompanied by an average emission of 7 protons. From Table 2 it can be seen that the fission cross section increases with increasing Z of the target nucleus. The total fission cross section for Sb with 660 Mev-protons is 0.25 millibarn. This value almost equals that determined on Ag for the same proton energies. (0.32 millibarn). The authors thank V. N. Mekhedov, L. D. Revina and L. P.

It is, however, of decisive 1,rrpor4A-nce that in Saviet production a sudden improvement of the quality of the devices for automation will have to take place. It cannot be explained, for instance, why the number of pH-meter3 produced is so small that they are not available In large nurbers for agriculture, although their extensive use woull ircraaase sojj_ productivity consider4bl,-.

After a olasaification-115"Te field, sintered carbides, cast carbides,, :stellites and their.derivatives deposited by fusion welding# and insog-t methods, for all,theae materials are separately,discussed. In the second part of the book.. thd application of hard_tjgj in 2 Gatting is presented in the.form of tables of to Iol geometry for all types ofiutting edges and- dimensional dravings and tables of every form of carbide tipped -tool. Detailed Listructions: for manufacture# attachment.. heat treatment and sharpening of ouch tools are given with full illustration of equipment, machinery and Inspection gauges Special attention is given to the Kolesov method of cutting large chip cross-sections .Hard-Cutting AUoys-in Engineering Production, and to the determination of standard cutting rates. The design of all common and special forms of milling cutters 4s. discussed in a separate chapterg together with cutter manufacturing procedure.. and standard milling rates and.conditions. Another chapter presents the special featurec of screw cutting folloired by a chapter,on drilling and the manufacture of drills including deep hole drilling and a great variety of counterboring tools.
