The capture γ rays of natural Mg are analyzed. The results indicate neutron separation energies of 7333.57 ± 0.07, 11 093.09 ± 0.08, and 6443.29 ± 0.12 keV for the 25Mg, 26Mg, and 27Mg products. From the primary intensities estimates of 51.5 ± 2.5 and 201 ± 9 mb for the 24Mg and 25Mg capture cross sections are deduced. Refined level energies for the three product isotopes are calculated and compared with previous results. Direct capture effects for electric and magnetic dipole and electric quadrupole transitions are discussed.

The neutron capture γ-rays from Li7, B11, and N15 have been studied. In Li7 γ-rays are observed at 7.26 ± 0.03 Mev. and 6.78 ± 0.05 Mev. In B11 six γ-rays are detected. The spectrum is consistent with J = 7/2 + for the capturing state. In N15 six previously unreported γ-rays are detected. Estimates of thermal neutron radiative capture cross sections are: Li6, 0.028 ± 0.008 b.; B10, 0.5 ± 0.2 b.; and N14, 0.08 ± 0.02 b.
