Abstract
  • The nuclear level structure of ¹⁰¹Ru has been investigated through the decay of 14.0 minute ¹⁰¹Tc produced by thermal neutron irradiation of molybdenum targets. Gamma-ray energies and relative intensities have been measured with the high resolution Ge(Li) spectrometers. Based on the energy sum and the intensity balancing, a consistent level scheme of ¹⁰¹Ru is proposed. Origins of spin-parity of the levels in ¹⁰¹Ru are discussed on the ground of de-Shalit weak coupling core excitation model. The results of this study are compared with the recent extended quasiparticle phonon coupling calculations. The gamma-ray energies and relative intensities emitted in the decay of 14.6 minute ¹⁰¹Mo have also been measured. Several new gamma transitions and level energies have been observed, and a new level scheme of ¹⁰¹Tc is proposed.
