摘要：

A method for semimicroscopic description of the spreading width of isobaric analog resonances (IARs) is applied to the IAR built on the 91Zr, 208,209Pb ground state. This width is expressed in terms of the mean Coulomb field and the imaginary part of the effective optical potential used to describe the total width of the IAR overtone-isovector giant monopole resonance. © 2009 Allerton Press, Inc.
