An sp-mixing model, which describes a compound nuclear reaction by mixing partial waves, predicts a correlation term in this reaction. The correlation term $$sigma_n$$ $$cdot$$ ($$k_n$$ $$times$$ $$k_gamma$$) in the $$^{139}$$La(n,$$gamma$$) reaction has been studied by measuring $$gamma$$-ray and neutron energies utilizing epithermal polarized neutrons and germanium detectors. The transverse asymmetry for single $$gamma$$-ray transition was measured to be 0.60 $$pm$$ 0.19 in the p-wave resonance.
