title = "Energy-dependent angular distribution of individual γ rays in the la 139 (n,γ) la 140 ∗ reaction",
abstract = "Neutron energy-dependent angular distributions were observed for individual γ rays from the 0.74 eV p-wave resonance of La139+n to several lower excited states of La140. The γ-ray signals were analyzed in a two-dimensional histogram of the γ-ray energy, measured with distributed germanium detectors, and neutron energy, determined with the time-of-flight of pulsed neutrons, to identify the neutron energy dependence of the angular distribution for each individual γ rays. The angular distribution was also found for a photopeak accompanied with a faint p-wave resonance component. Our results can be interpreted as interference between s- and p-wave amplitudes, which may be used to study discrete symmetries of fundamental interactions.",
