Observation of a spin-orbit splittinq of the 3p peak in the neutron strength function
Zo In Ok, Nikolenko V. G., Popov A. B., Samosvat G. S.
The/»-wave neutron strength functions for thepl/2 andp3/2 states have been determined separately from the average differential cross sections for elastic scattering of neutrons by nuclei in the mass range A ~ 50-130. The results reveal what is apparently the first demonstration of a spin-orbit splitting of an unbound state.
