For the energies and 77GEBc intensities of gamma rays with emitted by the capture of thermal 77GECc neutrons by 76Ge, I adopted the results of Groshev et al. (1972) 77GEDc [1972Gr34], and/or those of Hasselgren (1972) [1972Ha74]. As done with 77GEEc the gamma-ray intensities adopted for most other Ge isotopes, the 77GEFc intensities of Groshev et al. (1972) were doubled. I also doubled the 77GEGc normalization that Farhan and Singh (1997) [1997Fa12] had adopted for 77GEHc the intensities of Hasselgren (1972). Thus the adopted intensities are 77GEIc about twice those of Farhan and Singh (1997). 77GE c The intensities of Groshev et al. (1972) were based on 77GEAc intensities for the 73Ge(n,gamma)74Ge reaction of Magruder and Smither 77GEBc (1969) [1969Ma31]. As discussed by Islam et al. (1991) [1991Is01], all 77GECc gamma-ray intensities for Ge isotopes based on Magruder and Smither 77GEDc (1969) are too low. 77GE c Most gamma-ray energies are probably not known to better 77GEAc than ~1 keV. They generally agree with the few level assignments and 77GEBc level energies of Farhan and Singh (1997) to worse than ~1 keV. I 77GECc would estimate that the intensities have uncertainties of the order of 77GEDc 50% or more. The set is very incomplete, having only ~22% of the total 77GEEc energy and ~22% of the decays from the capture level. The sum of 77GEFc decays into the ground state is ~1%. 77GE N 1.0 77GE PN C 77GE2PN Per 100 neutron captures. 77GE G 431.50 1.640 77GE G 808.20 4.500 77GE G 850.80 3.240 77GE G 3895.20 2.144 77GE G 4514.30 0.480 77GE G 5420.10 1.488 77GE L 0.0 7/2+ 77GE L 159.70 1/2- 77GE G 159.50 0.640 77GE L 224.90 9/2+ 77GE L 421.00 (5/2+) 77GE L 491.90 77GE L 504.80 5/2+ 77GE L 581.00 (3/2-) 77GE L 618.80 (3/2-) 77GE L 629.40 3/2- 77GE L 760.50 (7/2+) 77GE L 778.00 (3/2-) 77GE G 195.60 0.300 77GE L 884.30 5/2+ 77GE L 1021.10 (3/2-) 77GE L 1047.60 (3/2-) 77GE L 1250.40 1/2+ 77GE L 1358.70 77GE L 1385.00 5/2+ 77GE L 1663.30 (3/2-) 77GE L 1823.30 1/2+ 77GE L 1883.00 77GE L 2060.00 77GE L 2816.70 77GE L 6072.60 77GE G 4008.50 1.488 77GE G 4193.20 4.944 77GE G 4821.80 0.320 77GE G 5049.10 5.386 77GE G 5444.70 0.496 77GE G 5912.85 9.266
