SCATTERING OF 65-MEV ALPHA PARTICLES FROM 89Y, 92ZR, 94ZR, 96ZR, AND 116SN

Differential cross sections for the scattering of 65-MeV α particles from Y89, Zr94, Zr96, and Sn116 were measured at 1°intervals between 10°and ∼75°. Angular distributions previously reported for Zr92 were extended to 112°. Several Woods-Saxon potentials were found to fit each elastic angular distribution. Distorted-wave calculations for the inelastic scattering were made with collective-model form factors. The deformation lengths βR0 are generally in agreement with the results of other experiments. Calculations using shell-model form factors were made for the 2+ and 4+ states in Zr94; a somewhat better fit to the data was obtained than with the collective model. © 1969 The American Physical Society.
