The nilsson-potential parameters for neutrons at A≃-100 and new deformation values for103Mo and105Mo

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The half-lives of the first excited levels in odd-neutron nuclei103Mo and105Mo have been measured. From these data, values of the deformation parameter ofɛ=0.31±0.05 and 0.29±0.06 for103Mo and105Mo, respectively, have been deduced assuming prolate spheroidal shapes. The present results in combination with previously determined properties of the ground-state bands of these nuclei are used to determineμ, the magnitude of the coefficient of the 12 term, in the Nilsson Hamiltonian, for the new region of deformation atA∼-100.
