✦ Synopsis

The 91 Zr(p, t) 89 Zr reaction has been studied in a high-resolution experiment at an incident proton energy of 25 MeV. Angular distributions for transitions to 44 levels of 89 Zr up to an excitation energy of ∼ 3.650 MeV have been measured. DWBA analysis, with conventional Woods-Saxon potentials, allowed the assignment of the transferred angular momenta L. The energy spectrum of 89 Zr has been studied in the framework of the shell model, using the large-basis shell-model code OXBASH. The structure of both positive-and negative-parity states of 89 Zr has been investigated using the PMM90pn residual interaction, and discussed in comparison with the experimental findings from the 91 Zr(p, t) 89 Zr reaction.
