EXCITATIONS OF SM-144 IN (P,P')

The reaction 144Sm(p,p') has been studied with an energy resolution of 4-5 keV using 22 MeV protons. Angular distributions for states up to 4 MeV excitation energies are compared with distorted-wave and coupled -channels calculations including one-step and two-step excitations to study direct and sequential strength distributions. The results are co mpared with calculations in the nuclear field theory approach where qu asiparticle-random-phase-approximation-like states and their mixing wi th two-phonon (quadrupole and octupole) states is taken into account. Reasonable agreement is obtained for both the positive and the negativ e parity states.
