The {sup 150}Sm(n,n'{gamma}) reaction was measured from E{sub n} = 1 to 15 MeV at the Los Alamos Neutron Science Cemter (LANSCE). The {gamma} rays were detected with the Compton-suppressed Germanium Array for Neutron Induced Excitations (GEANIE). Measured {gamma}-ray excitation functions were converted to partial {gamma}-ray cross sections, Twenty four individual {gamma}-rays up to E{sub x} = 1.8 MeV in {sup 150}Sm were measured. Results are compared with enhanced Hauser Feshbach model calculations: the spin distribution in the pre-equilibrium reaction is calculated with the quantum mechanical model of Feshbach, Kerman and Koonin. The particle transmission coefficients were calculated with two different global optical model potential parameter sets. We employed the coupled-channel optical model based on the soft rotor model and with spherical potential.
