The elastic and inelastic scattering of cx-particles by a vibrational nucleus is calculated using plane-wave Born approximation. The excitation of both single-phonon and twophonon states is considered. The effect of the diffuseness of the nuclear surface is included. The result for elastic scattering and the excitation of the single-phonon 2+ and 3- states is in good agreement with experiment for .oNi. The approximations used are discussed, and it is suggested that excitation of 0+, 1-, and 5- states should provide the best experimental test of the theory of two-phonon excitation of nuclei. The energies of the vibrational states are also considered.

In order to obtain information about the levels of even spin and parity of 8 Be at energies above 11 MeV, the differential cross-section for the α-particle-helium elastic scattering has been measured at a series of beam energies from 23·1 to 38·4 MeV, for many c.m.s. angles between 30 and 90°. Phase shifts up to L = 8 have been calculated for each energy. Combining these results with previous figures for lower energies, the phase shifts δ 0 , δ 2 and δ 4 are thus known as functions of incident energy from 0·15 MeV to 38·4 MeV. The behaviour of the phase shift δ 4 confirms the existence of a previously suggested level with I = 4 at an excitation energy of about 11·4 MeV in 8 Be. The phase shifts δ 6 and δ 8 are small, as expected if the rotational series of levels in 8 Be term inates with I = 4.
