Abstract

An excitation function for resonance elastic scattering of α particles on O18 and Ne18 was measured using the method of inverse geometry with a very thick target. Spectroscopic information was obtained for 23 levels in the excitation energy region from 11.9 to 13.7MeV in Ne22. Twelve of them are new. General features of α-cluster bands in Ne22 are analyzed in the framework of the potential model with a deep potential well. Predictions for the 11− level in Ne22, as well as for the isotopic shift of the cluster levels in Mg22, are given. Evidence is presented that new perspectives on the study of nuclear structure and nuclear spectroscopy can be obtained in complimentary measurements of α-cluster states in mirror N≠Z nuclei.3 MoreReceived 10 July 2003DOI:https://doi.org/10.1103/PhysRevC.69.024602©2004 American Physical Society
