ABS>Inelastic scattering and elastic scattering of 43-Mev alpha particles have been studied over the angular range from 17 deg to 53 deg cm. The angular distributions of the prominent group from the 2/sup +/ first excited level and the 3/sub -/ anomalous'' group are fitted well by calculations based on the distorted-wave Born approximation. The angular distribution of the 4/sup +/ group of 5.5 Mev in Ni/sup 58/ also agrees well with the calculations. Groups at low excitation, with angular distributions in phase with elastic scattering, were found at 2.2 and 2.50 Mev in Ni/sup 60/ and at 2.47 Mev in Ni/sup 58/. These groups violate the phase rule from Fraunhofer diffraction theory, and hence are believed to be due to two-phonon excitations. Other groups with angular distributions in phase with elastic scattering were found at 4.45, 6.8, and 7.1 Mev in Ni/sup 56/ and at 4.05, 5.6, 6.2, and 7.0 Mev in Ni/sup 60/. Groups with angular distributions out of phase with elastic scattering were found at 1.45, 3.3, 5.5, and 5.9 Mev in Ni/sup 56/ and at
