SUPERSYMMETRY IN SE-74, SE-75, AS-73, AND AS-74 NUCLEI

New experimental data, obtained on As-73 and As-74, were used to test the predictions of the U-pi(6/12)xU(nu) (6/12) supersymmetry scheme in its vibrational limit. The level spectra of Se-74(34)40, Se-75(34)41, As-73(33)40 and As-74(33)41 supermultiplet nuclei have been calculate d using a simple closed energy formula. 44 states in four different nu clei have been reasonably described using only 7 fitted parameters. Th e existence of supersymmetry was supported also by one-nucleon transfe r reaction data, electromagnetic properties, and by a comparison betwe en the supersymmetry and interacting boson-fermion-fermion model wave functions.
