Phys. Rev. C 61, 067302 (2000) [4 pages]Energy shifted level densities in rare earth regionReceived 1 November 1999; revised 23 February 2000; published 3 May 2000 The energy shift between the level densities of the even-odd and even-even isotopes 161,162Dy and 171,172Yb is measured as a function of excitation energy. The results are compared with predictions from various semiempirical models. The energy shift procedure works well for excitation energies between 3.5 and 7 MeV in the even-even nucleus, yielding a relative energy shift close to the experimental pairing gap parameter Δ. © 2000 The American Physical Society URL:
