Abstract
Magnetic dipole strength functions have been deduced from averages of a large number of transition strengths calculated within the shell model for the nuclides Zr, Mo, Mo, and Mo. An enhancement of strength toward low transition energy has been found for all nuclides considered. Large strengths appear for transitions between close-lying states with configurations including proton as well as neutron high- orbits that re-couple their spins and add up their magnetic moments coherently. The strength function deduced from the calculated transition strengths is compatible with the low-energy enhancement found in (He,He') and experiments. The present work presents for the first time an explanation of the experimental findings.
