Precise Neutron Lifetime Measurement Using Pulsed Neutron Beams at J-PARC

N. Sumi, K. Hirota, G. Ichikawa +18

A neutron decays into a proton, an electron, and an anti-neutrino through the beta-decay process. The decay lifetime ( $\sim$ 880 s) is an important parameter in the weak interaction…

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

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

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