Alpha-particle angular distributions with respect to spin direction
- 1. Department of Chemistry, Washington University, St. Louis, Missouri 63130
Description
Angular distribution of alpha particles with respect to the spin direction of residual nuclei from fusion of 176-MeV 20Ne with 150Nd has been measured with the spin spectrometer. Below the Coulomb barrier, the ratio of the 900 to 00 yields with respect to spin direction increases with decreasing E/sub α/. This effect is not shown by a statistical-model calculation using penetrabilities for spherical potentials, which suggests that the α-emitting nuclei are deformed with their longest axis perpendicular to the spin direction. If so, the deformation increases as the spin rises from approx.34 to 64h
