Shell model study of /sup 90/ /sup 88/Zr
Conventional spherical shell model calculations have been undertaken to describe /sup 90/Zr and /sup 88/Zr. Valence orbitals included the 1f/sub 5/2/, 2p/sub 3/2/, 2p/sub 1/2/, and lg/sub 9/2/ for protons, and lg/sub 9/2/ and 2d/sub 5/2/ for neutrons. For /sup 90/Zr, the number of lg/sub 9/2/ protons was less than or equal to 2. For the high spin even parity states of /sup 90/Zr, two calculations were performed, one with less than or equal to 4 (0) g/sub /9/2/ protons (neutron holes) and one with less than or equal to 2 (2) g/sub 9/2/ protons (neutron holes). For /sup 88/Zr, the number of particles in the g/sub 9/2/ shell was restricted to less than or equal to 10. For the high spin negative parity states, a calculation was done with up to 11 particles in the g/sub 9/2/ shell. A realistic two-body interaction was employed in this calculation. Predicted excitation energies are compared with experimental results, and for the lower lying positive parity states a comparison of electromagnetic transition rates is also made.
