Abstract
We present a statistical analysis of proton resonances in the compound nucleus Tc-93 in terms of random matrix theory (RMT). The fluctuation properties of energy levels and reduced widths from data measured by Bilpuch et al. [Phys. Rev. C 9 (1974) 1589] are studied. We conclude that one T> = 9/2 isobaric analog state does not affect the spectral correlations of a sequence of 124 T< = 7/2 states, and that the observed deviations from RMT are due to unobserved levels. For the reduced widths, however, certain deviations from Porter-Thomas statistics are attributed to the effect of isospin mixing. (C) 2004 Elsevier B.V. All rights reserved.
