Investigation of anomalousK,L andM shell conversion in electric dipole transitions

Anomalous experimental conversion coefficients of theK, L andM subshells are investigated for thirteen highly hindered electric dipole transition in six deformed odd mass nuclei. For a distinct nuclear transition, all experimental anomalies are consistent with one parameter, containing all nuclear information. The values of this parameter are determined and a simple connection with the hindrance of the transition seems to exist. TheK andL shell conversion coefficients have been recalculated, while theM shell conversion data were newly computed including all finite nuclear size effects as well as screening by a Thomas-Fermi-Dirac model.
