Abstract

New electron scattering data are presented for levels of 154Gd. The study includes the three lowest-lying 2+ levels at 0.123, 0.816, and 0.996 MeV excitation energies. These data provide a test of the Interacting Boson Approximation (IBA) prediction that three electric quadrupole transition charge densities are clearly dependent. Deviation of the experimental densities from linear dependence is presented and discussed.

Funding Information:
Experimental examination of the Interacting Boson Approximation (IBA) has focussed primarily on long wavelength observables: nuclear energy level spacings and decay branching ratios \[1,2\]a nd two particle transfer strengths \[3\].P resent success of the IBA rests on a favorable comparison of its calculated matrix elements with these observables. Such nuclear observables involve integrals of the nuclear wave functions. The IBA predictions are equivalent to integrals of boson wave functions.
