For the energies and 75GEBc intensities of most gamma rays with energies above 4700 keV emitted by 75GECc the capture of thermal neutrons by 74Ge, I adopted the results of 75GEDc Islam et al. (1991) [1991Is01]. For most other gamma rays, I adopted 75GEEc the energies and twice the intensities of Groshev et al. (1972) 75GEFc [1972Gr34]. For four gamma rays with energies less than 317 keV, I 75GEGc adopted the energies and twice the intensities of Weishaupt and 75GEHc Rabenstein (1972) [1972We10]. For 16 gamma rays with energies below 75GEIc 1502 keV from levels of 1502 keV or lower that were not in the above 75GEJc references, I added gamma rays using the sum of the intensities of 75GEKc gamma rays into these levels and the gamma rays from the de-excitation 75GELc of these levels of Farhan and Rab (1990) [1990Fa07]. 75GE c Except for the results using Islam et al. (1991) and the 16 75GEAc decay gamma rays, these intensities are 2.0 times those adopted by 75GEBc Farhan and Rab (1990), who adopted the intensities of Groshev et al. 75GECc (1972), which were based on intensities for 73Ge(n,gamma)74Ge of 75GEDc Magruder and Smither (1969) [1969Ma31]. As discussed by Islam et al. 75GEEc (1991), all gamma-ray intensities for Ge isotopes based on Magruder 75GEFc and Smither are too low. The intensities adopted here are consistent 75GEGc with the measurements using natural germanium of Rasmussen et al. 75GEHc (1969) [1969Ra10]. 75GE c These adopted intensities are higher than but consistent 75GEAc with those of gamma rays above 5620 keV of Barchuk et al. (1970) 75GEBc [1970Ba]. The adopted intensities for gamma rays with energies above 75GECc 3300 keV are generally consistent with 0.35 times the results of 75GEDc Hasselgren (1972) [1972Ha74]. 75GE c Most gamma-ray energies are probably not much better than 75GEAc ~0.5 keV. They generally agree with the level assignments and level 75GEBc energies of Farhan and Rab (1990) to ~0.5 keV. The intensities of the 75GECc high-energy gamma rays of Islam et al. (1991) are reported to be good 75GEDc to about 10%. I would estimate that most other intensities have 75GEEc uncertainties of ~25-50%. The set is not complete, missing about 41% 75GEFc of the total energy and over half of the gamma rays from the capture 75GEGc level. The sum into the ground state is 79%. The sums into and out of 75GEHc various levels usually do not agree well. 75GE N 1.0 75GE PN C 75GE2PN Per 100 neutron captures. 75GE G 111.80 0.800 75GE G 121.10 0.860 75GE G 737.10 2.620 75GE G 932.70 1.860 75GE G 1222.00 8.700 75GE G 3302.90 0.860 75GE G 3337.70 1.060 75GE G 3348.30 0.720 75GE G 3502.20 0.800 75GE G 3553.30 1.160 75GE G 3607.50 0.880 75GE G 3635.50 0.580 75GE G 3826.10 0.560 75GE G 3934.90 0.920 75GE G 4436.40 3.020 75GE G 4747.63 0.780 75GE G 4816.86 3.058 75GE L 0.0 1/2- 75GE L 61.89 75GE L 139.69 7/2+ 75GE G 139.20 14.181 75GE L 192.22 5/2+ 75GE L 199.89 9/2+ 75GE L 253.10 3/2- 75GE G 253.70 18.600 75GE L 316.79 5/2- 75GE G 124.70 0.560 75GE G 177.30 4.360 75GE G 316.90 3.160 75GE L 457.05 5/2- 75GE G 204.00 1.900 75GE G 455.80 3.180 75GE L 574.67 3/2- 75GE G 574.70 26.600 75GE L 584.45 5/2+ 75GE G 445.20 4.680 75GE L 651.00 (7/2-) 75GE L 673.67 1/2+ 75GE G 481.40 0.790 75GE G 673.80 0.260 75GE L 762.24 3/2 75GE G 762.40 2.680 75GE L 885.46 1/2- 75GE G 299.70 0.280 75GE G 310.70 0.530 75GE G 632.30 0.370 75GE G 885.60 0.890 75GE L 901.30 75GE L 987.00 (7/2+) 75GE L 1062.20 75GE L 1080.60 75GE L 1127.80 75GE L 1136.88 3/2- 75GE G 236.10 0.230 75GE G 562.00 0.150 75GE G 679.80 0.350 75GE G 820.10 1.130 75GE G 1136.90 0.590 75GE L 1240.72 5/2- 75GE L 1257.00 (9/2+) 75GE L 1335.20 75GE L 1394.41 5/2+ 75GE L 1416.23 (3/2-) 75GE G 841.60 3.120 75GE L 1427.36 75GE G 1174.60 0.680 75GE G 1427.00 0.400 75GE L 1494.60 75GE L 1501.54 (3/2-) 75GE G 927.20 7.700 75GE G 1043.30 3.000 75GE G 1248.80 6.400 75GE G 1501.10 5.240 75GE L 1514.45 1/2+ 75GE L 1537.70 5/2+ 75GE L 1603.00 (7/2-) 75GE L 1718.43 5/2+ 75GE L 1796.27 (3/2-) 75GE G 1545.00 6.340 75GE L 1869.44 3/2+ 75GE L 2003.93 3/2+ 75GE L 2094.80 75GE L 2103.70 75GE L 2110.10 75GE L 2197.10 75GE L 2214.80 5/2+ 75GE L 2382.90 5/2+ 75GE L 2527.28 (5/2+) 75GE L 2574.20 (5/2+) 75GE L 2660.79 (3/2-) 75GE L 2665.00 75GE L 2748.50 (5/2+) 75GE L 2759.10 75GE L 2834.00 75GE L 2852.80 (3/2-) 75GE L 3031.80 1/2+ 75GE L 3048.80 1/2+ 75GE L 3067.40 75GE L 3082.30 75GE L 3162.40 (3/2-) 75GE L 3279.60 7/2- 75GE L 3290.30 3/2+ 75GE L 6505.50 75GE G 3745.30 0.620 75GE G 3846.80 1.020 75GE G 3979.50 0.400 75GE G 4410.60 2.020 75GE G 4707.00 7.140 75GE G 4990.00 1.970 75GE G 5003.22 2.270 75GE G 5075.90 1.080 75GE G 5088.00 4.350 75GE G 5368.00 2.450 75GE G 5620.09 2.349 75GE G 5745.00 0.610 75GE G 5930.34 2.910 75GE G 6252.16 11.751 75GE G 6505.09 2.830
