abstract

  • The reaction 165Ho (3He,d) 166Er was studied using the University of Rochester Tandem Van de Graaff accelerator and an Enge-type split-pole magnetic spectrograph. The observed cross sections for the ground state rotational band and the gamma vibrational band were consistent with predictions based on the unified nuclear model. The population of the 1574 keV level was consistent with that expected for the K^π=4^-, 7/2-[523] + 1/2+[411] assignment obtained from decay scheme studies. The K^π=2^- octupole vibrational band based on the 1460 keV state was not populated as strongly as expected, indicating that the admixture of the 7/2-[523] - 3/2+[411] two proton state into this vibration is only about one-fifth as large as predicted by Soloviev et al.
