Abstract

Using results derived earlier, we investigate the influence of isospin mixing in the compound nucleus upon the autocorrelation functions for isospin-allowed and isospin-forbidden reactions. We exhibit how these functions depend on the degree of isospin mixing, and that they need not have the simple lorentzian form commonly considered. The available experimental data relating to the compound nucleus ³⁰P are examined in the light of these results.

Doorway-state analysis of the fragmentation of the magnetic-dipole strength in SU58 NI observed in high-resolution inelastic electron scattering
1986, Nuclear Physics, Section A
The fine structure of the magnetic-dipole strength in ⁵⁸Ni observed in high-resolution inelastic electron scattering at the DALINAC has been analysed under the assumption that the measured distribution of the strong fragmented M1 strength results from a coupling of two doorway states to a large number of more complicated states. From the doorway-state analysis one obtains the coupling matrix elements between doorway states |d〉 and complicated states |q〉. This allows the calculation of the escape width Γ^↑ and the spreading width Γ^↓ of the assumed doorway states. The influence of a coupling between the doorway states via the complicated states (internal mixing) is discussed. An estimate of a mean coupling matrix element between the two doorway states is given.
