dc.description.abstract <p>Radioactivities were produced by the fast (pile) neutron bombardmant of germanium.. Chemical separations followed by decay and absorption measurements yielded the following results. Eleven-day Ge-71 decays with the emission of positrons with maximum energy of 0.65-Mev Ge-77 with 12 hour half-life emits 0.31 Mev gamma-rays. The half-life of As-77 i s 38.0 plus or minus 0.5 hours and it emits 0.68 Mev beta particles and two gamma rays. The following new gallium and zinc activities were observed, but not as signed definite mass numbers. A 14.5 day gallium activity emits beta particles with energies of 0.29 and 0.71 Mev, 34 Kev gamma rays and possibly X-rays; a 53 hour gallium activity gives off' 1.9 Mev beta particles and 1.63 Mev gamma rays; a 14-day zinc activity decays 'Wi.th the emission of 2.1 Mev particles and 40 Kev gamma rays.</p>
