The Spin Spectrometer was used to measure the angular distribution of alpha particles with respect to the spin direction of residual nuclei from fusion of 176-MeV /sup 20/Ne with /sup 150/Nd. The results show an enhancement of the ratio of 90/sup 0/ to 0/sup 0/ alpha yields with respect to spin direction with decreasing E/sub ..cap alpha../ at subbarrier energies. This effect is not reproduced by statistical-model calculation made with transmission coefficients for spherical potentials, which may indicate that the ..cap alpha..-emitting nuclei are deformed with their longest axis perpendicular to the spin direction. 15 references.
