Abstract

The neutron differential elastic scattering cross section of O16 has been measured at and in the vicinity of the 1-Mev resonance as well as at higher nonresonant energies. A phase-shift analysis of the results gives the s12, p12, p32, and d32 phase shifts up to 2.4-Mev neutron bombarding energy. The bound single-particle states of O17, as well as the s- and d-wave phase shifts, determine the parameters of a phenomenological potential well which describes the average interaction of the neutron with the O16 core. This potential has a depth around 40-45 Mev, which varies slightly for different single-particle configurations, and has a diffuse boundary with a Thomas-type spin-orbit energy term. It is consistent with the potentials which in other work are found to fit data of much higher mass.
