✦ Synopsis

The spreading width of analogue states due to the Coulomb interactions in a nucleus is calculated. The coupling to single-particle, two-particle-one-hole and three-particle-twohole configurations is considered. The effect of nuclear interactions is taken account in the large energy separation between the analogue and the configuration states (symmetry energy displacement) and in the natural distribution of the latter representing their fragmentation. The spreading widths are found to be small, less than 3 keV in sgy and 91Nb.
