REACTIONS 12C(N,GAMMA)13C AND 19F(N,GAMMA)20F

Gamma rays from thermal-neutron capture in 12C and 19F have been studied with a Ge(Li) detector. In the 19F(n, γ)20F reaction, 73 γ-lines were found, of which 66 could be fitted into the level scheme of 20F. The energies of two γ-rays observed in the 12C(n, γ)13C reaction are determined as 1 261.76±0.07 and 3 684.28±0.10 keV. The energy of the γ-ray emitted from 16O produced in the reaction 19F(n, α)16N(β-)16O* is determined as 6 129.6±0.4 keV. The Q-values of the following reactions have been determined: {A table is presented}. © 1968.
