Abstract
A superconductor with a sharp peak in the density of electron states a nd with paramagnetic impurities is considered. Critical temperature T- C values and the isotopic shift factor alpha are analyzed as a functio n of the Fermi-level position relative to the peak center and of the i mpurity concentration. Experimental results for isotopic factor alpha in LSCO:Fe system are analyzed.
