 74GA c  Isomeric activity produced by {+74}Ge(n,p) reaction using 14-MeV
 74GA2c  neutrons (1974Va08). Authors report |g-ray, x-ray, |b{+-}, |b|g, |g|g,
 74GA3c  and sum peak measurements
 74GA c  1977Va01 use delayed coincidence summing technique (1978Ta08) to
 74GA2c  measure T{-1/2} of 56.5 level. A single activated germanium detector
 74GAxc  was used
 74GA cG $No K x-rays observed with T{-1/2}|?10 s
 74GA cG $From an attempt to observe |b radiations from the isomer,
 74GA2cG 1974Va08 estimate I(|b{+-})<50%
 74GA cG $No |b|g and |g|g coincidences observed with 56.5|g (1974Va08)

 74GA2cG activated germanium detector
