Energy dependent angular distribution of individual $\gamma$-rays in the ${}^{139}$La($n$, $\gamma$)${}^{140}$La* reaction

T. Okudaira, S. Endo, H. Fujioka +14

Neutron energy-dependent angular distributions were observed for individual $\gamma$-rays from the 0.74 eV p-wave resonance of ${}^{139}$La+$n$ to several lower excited states of ${}^{140}$…
