Abstract
We measured the spin dependence in a neutron-induced -wave resonance by using a polarized epithermal neutron beam and a polarized nuclear target. Our study focuses on the 0.75~eV -wave resonance state of La+, where largely enhanced parity violation has been observed. We determined the partial neutron width of the -wave resonance by measuring the spin dependence of the neutron absorption cross section between polarized and polarized neutrons. Our findings serve as a foundation for the quantitative study of the enhancement effect of the discrete symmetry violations caused by mixing between partial amplitudes in the compound nuclei.
