AbstractAbstract
[en] The 1966 version of Nuclear Data Sheets for A = 74 has been revised on the basis of experimental data received prior to December 1, 1975. Results from approximately 95 papers and communications have been included in the present evaluation. Data on seven A = 74 nuclei are presented. The main features of the decay schemes for 74Zn and 8.1-m 74Ga appear to be known. An upper limit of 50 percent has been established for the β-decay branching ratio for 9.5-s 74Ga. Both β+- and β--decays of 74As are well established. Many excited levels are known in 74Ge, 74As, and 74Se from a variety of decay and reaction experiments, but few spin assignments are firm. The level identification for a 26.8-ns isomer in 74As is uncertain. An 8.0-s activity previously assigned to 74As is now believed to occur in 197Au. The decay schemes for two 74Br isomers are reasonably well established, but the energy difference between the two isomers is not well known. The decay scheme for 74Kr is well established, but results on excited levels in 74Kr are contradictory
