ELASTIC AND INELASTIC SCATTERING OF 20.3-MEV POLARIZED PROTONS FROM 90ZR, 92ZR, AND 92MO

The elastic and inelastic scattering of polarized protons from Zr90, Zr92, and Mo92 has been studied at 20.3 MeV. Asymmetries for the first 2+ states in Zr90 and Mo92 are very similar; the Zr92 2+ asymmetry is quite different from these, especially at large angles. The asymmetry for the first 3- state in Zr92 resembles the Zr90-Mo92 3- data more closely. Microscopic-model calculations for the 2+ states with and without core-polarization contributions give poor fits to the asymmetry data, though cross sections are well fitted. Macroscopic-model calculations with the full Thomas form of the deformed spin-orbit potential give a better fit to the 2+ data and quite closely predict the 3- asymmetries. © 1969 The American Physical Society.
