MICROSCOPIC DESCRIPTION OF THE EXCITATION OF SOME STATES IN THE ZR-90,ZR-92,ZR-94,ZR-96 ISOTOPES

We describe the application of a realistic self-consistent theory of f inite Fermi systems to the ground and low excited states of the Zr-90, Zr-92,Zr-94,Zr-96 isotopes. Results were obtained for the ground, 2(1) (+) and 3(1)(-) states in each nucleus, and for the lowest 4(+), 5(-), 6(+) and 8(+) states in Zr-90. Transition densities were generated fo r the excitation of each of these states and their properties examined . Transition potentials for their excitation by hadronic inelastic sca ttering were constructed by folding with appropriate interactions betw een the projectile and each target nucleon, The calculated inelastic s cattering cross sections are compared in detail with experimental resu lts, particularly those for alpha particles at 35.4 MeV and Li-6 at 70 MeV. The implications of any discrepancies found are discussed. In ad dition, the theoretical results were used as ''experimental'' data in order to test the validity of using various simple models for the anal ysis of data.
