Gamma spectroscopic study of105Ru

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

Theγ radiation following thermal neutron capture in104Ru has been investigated through singles, coincidence, and angular correlation measurements in order to solve existing discrepancies and to complete the knowledge about the transitional odd-N nucleus 10544 Ru61. The resulting level andγ-decay scheme is found to be very similar to that of the odd-Z transitional nucleus 14961 Pm88. Between the 11/2−, 15/2−, and 19/2− states which are interpreted as members of the decoupled band, built on the unique parity 11/2− single particle state, low spin states of negative parity are found at surprisingly low excitation energies above the 11/2− state. In the frame of the particleplus-rotor model their positions would require a sharp decrease of the rotational parameter with increasing collective angular momentum of the soft core.
