For intensities of stronger gamma rays with 21NEDc energies above 2000 keV, I adopted those of Prestwich et al. (1986) 21NEEc [1986Pr05]. For intensities of gamma rays below 2000 keV and weaker 21NEFc gamma rays above 2000 keV, I adopted those confirmed by an intensity 21NEGc balance by Selin (1970) [1970Se14] and normalized his relative 21NEHc intensities by 0.10. These data are generally consistent with those of 21NEIc Bellmann (1971) [1971Be34] and Jonsson et al. (1967) [1967Jo09]. 21NE c The data set is only ~95% complete. The adopted energies 21NEAc are probably good to better than ~0.5 keV as the level energies of 21NEBc Endt (1990) used here are generally reported to be good to a few 21NECc tenths of a keV. The intensities of Prestwich et al. (1986) are 21NEDc reported to have errors of a few percent. Selin (1970) did not give 21NEEc any uncertainties. I estimate the uncertainties in the adopted 21NEFc intensities to be ~5% for the stronger gamma rays (>1% per capture) 21NEGc and more for weaker gamma rays. 21NE N 1.0 21NE PN C 21NE2PN Per 100 neutron captures. 21NE L 0.0 3/2+ 21NE L 350.73 5/2+ 21NE G 350.72 57.836 21NE L 1745.91 7/2+ 21NE L 2788.83 1/2- 21NE G 2437.95 1.000 21NE L 2794.14 1/2+ 21NE G 2793.94 25.000 21NE L 2866.80 9/2+ 21NE L 3663.67 3/2- 21NE G 874.82 0.229 21NE G 3312.66 0.170 21NE L 3735.30 5/2+ 21NE G 3734.94 0.114 21NE L 3884.30 5/2- 21NE L 4433.60 11/2+ 21NE L 4525.40 5/2+ 21NE L 4684.50 3/2+ 21NE G 4333.29 0.320 21NE G 4683.94 0.250 21NE L 4725.36 3/2- 21NE G 1931.12 16.400 21NE G 4374.14 52.900 21NE G 4724.79 0.140 21NE L 5335.70 7/2- 21NE L 5430.80 5/2+ 21NE L 5549.00 3/2+ 21NE L 5629.00 7/2+ 21NE L 5689.77 1/2+ 21NE G 2895.42 7.000 21NE G 5688.94 5.950 21NE L 5774.70 21NE L 5819.00 7/2- 21NE L 5822.00 3/2+ 21NE L 5992.56 3/2- 21NE G 2257.13 0.229 21NE G 2328.75 0.229 21NE G 5641.02 0.240 21NE G 5991.64 0.440 21NE L 6032.90 9/2- 21NE L 6173.80 7/2 21NE L 6267.40 9/2+ 21NE L 6447.60 11/2 21NE L 6551.70 9/2 21NE L 6608.10 5/2 21NE L 6640.00 9/2 21NE L 6761.10 21NE G 587.29 0.800 21NE G 768.52 1.943 21NE G 1071.30 13.487 21NE G 2035.63 73.800 21NE G 2076.49 0.800 21NE G 3025.57 0.229 21NE G 3097.18 0.230 21NE G 3966.56 0.390 21NE G 3971.87 1.080 21NE G 6409.32 0.500 21NE G 6759.93 5.840
