Conversion electron measurement of isomeric primary transitions in196, 198, 199, 200, 201Pb

Abstract

The transition energies of nine low energy primary transitions from high spin isomers in196, 198, 199, 200, 201Pb have been measured with conversion electron spectroscopy usinge−e− ande−γ coincidences.B(E2) values as deduced from the measured lifetimes and transition energies are discussed in terms of seniority shell model configurations and of a quasiparticle Tamm-Dancoff approach using the surface delta interaction. A revised discussion of the effectiveE2 charge in neutron deficient Pb isotopes is presented.
