Measurement of nuclear spin relaxation time in lanthanum aluminate for development of polarized lanthanum target

K. Ishizaki, H. Hotta, I. Ide +10

The nuclear spin-lattice relaxation time ( $T_{1}$ ) of lanthanum and aluminum nuclei in a single crystal of lanthanum aluminate doped with neodymium ions is studied to estimate the fe…

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 $^{140}$ …

Transverse asymmetry of $γ$ rays from neutron-induced compound states of $^{140} La$

T. Yamamoto, T. Okudaira, S. Endo +17

A correlation term $σ_{n} \cdot (k_{n} \times k_{γ})$ in the $^{139} La (n, γ)$ reaction has been studied utilizing epithermal polarized neutrons and germanium det…
