84SR C 1976IA01: 84Y produced by 84SR(P,N) reaction. Measured EG, IG, T.
84SR c 1981Li12: measured |b|g coin, deduced Q value
84SR C 1981DEZD: 84Y produced by decay chain 84MO->84NB->84ZR->84Y produced
84SR2C in reaction 54FE(32S,2N). Measured G and B+ spectra in coincidence
84SR3C with mass. Deduced Q values and relative B feedings.
84SR c 1982De36 (same group as 1981DeZD): {+84}Y isotope obtained from the
84SR2c decay of {+84}Zr produced in a {+54}Fe+{+32}S reaction. Measured
84SR3c |b|g coin, deduced Q value
84SR C 2000Do10: 84Y produced by decay of 84ZR produced in 58NI(32S,4P2N)
84SR2C reaction. Measured EG, IG, GG using 5 ^HPGe detectors and a low
84SR3C energy photon spectrometer. The authors claim to have observed 50 |g
84SR4C rays from decay of 39.5-min and 4.6-s activities of 84Y, but
84SR5C details of this study are not available either in the
84SR6C (conference) paper or according to an e-mail reply from the first
84SR7C author on May 24, 2003
84SR C The decay scheme is considered by the evaluators as incomplete.
