83KR c 1976Va03: {+83}Br activity from neutron irradiation of natural Se
83KR2c target followed by chemical separation. Measured E|g, I|g, |g|g, Ece,
83KR3c Ice using a Ge(Li) detector, a low-energy Ge(Li) detector and a
83KR4c Si(Li) detector for |g rays, a surface-barrier Si detector for
83KR5c conversion electrons and a Ge(Li)-NaI(Tl) detector system for |g|g
83KR6c coincidences.
83KR c 1988Al01: precise measurements of E|g using a Ge(Li) detector.
83KR c 1990Me15: precise measurements of E|g and I|g using Ge(Li) detectors.
