Low Lying Negative Parity States in the Nucleus 90/40Zr

摘要

A shell model scheme involving a large model space (2psub(1/2)1gsub(9/2)1hsup(x)sub(11/2))sup(n) with x=1 for both proton and neutron configuration is employed. M10 amplitude for the transition 10 exp - to 0 exp + g.s. is well reproduced on the model and the possibility of collective structures for most of the states with J<=7 exp - is indicated.
