An sp-mixing model, which describes a compound nuclear reaction by mixing partial waves, predicts a correlation term in this reaction. The correlation term ( ) in the La(n,) reaction has been studied by measuring -ray and neutron energies utilizing epithermal polarized neutrons and germanium detectors. The transverse asymmetry for single -ray transition was measured to be 0.60 0.19 in the p-wave resonance.
