Analogues of Excited States in 91Zr

Abstract

The level structure in 91Zr has been investigated by Cohen and Chubinsky (1963) with the 90Zr (d, p)91Zr reaction. They noted some 14 levels up to an excitation energy of 3·9 MeV. All these states were found to have positive parity and their structure is fairly well understood in terms of coupling a single-particle neutron to the ground state and the first two excited states of 90Zr (Ramavataram 1964). A study of the isobaric analogues of the 9lZr states with the 90Zr(p, pO)90Zr reaction was carried out by Moore (1964).
