Abstract
A study has been made of the 90 Zr(n,d) 89 Y reactlion at an
incident neutron energy of 22 MeV. The experimental
aspect of the study was performed at the Van der Graaf
facility at the National Accelerator Centre, using a
particle spectrometer developed by K Bharuth-Ram and
W R McMurray for the study of neutron-induced charged-particle
emissions. The spectrometer, which consists of
a telescope of three multiwire proportional counters and
a curved plastic scintillator, permits the simultaneous
accumulation of data over an angular range of 80°. Solid-angle-
calculations have been performed to correct for the
effect of the geometry of the system on the angular
distribution of the cross-sections. A review has been made
of the shell model of the nucleus, the optical potential model
and the distorted waves method (or DWBA) for the analysis
of direct nuclear reactions. A distorted-waves method
analysis of the reaction is performed with the code DWUCK 4
and the resulting angular distribution of the various
cross-sections are compared with the experimentally obtained
data. ThIs comparison produces spectroscopic factors which
are used to perform some analysis of the nuclear structure
of the 90 Zr nucleus.
