(1982) 13C Bc [1982Mu14]. The intensities of the three major gamma-ray lines are 13C Cc consistent with those of Thomas et al. (1967) [1967Th05], Rasmussen et 13C Dc al. (1969) [1969Ra10], and Jurney et al. (1982) [1982Ju01]. These 13C Ec intensities differ by only a few percent. 13C c The gamma-ray energies were calculated from the energies of 13C Ac the levels and capture state as reported by Ajzenberg-Selove (1991) 13C Bc [1991Aj01]. The energies of these levels are known to ~0.1 keV. The 13C Cc data appear complete and very good. 13C N 1.0 13C PN C 13C 2PN Per 100 neutron captures. 13C L 0.0 1/2- 13C L 3089.44 1/2+ 13C G 3089.05 0.430 13C L 3684.51 3/2- 13C G 595.05 0.240 13C G 3683.95 32.140 13C L 3853.81 5/2+ 13C L 4946.31 1/2+ 13C G 1261.74 32.360 13C G 1856.72 0.160 13C G 4945.30 67.470
