New experimental data, obtained on73As and74As, were used to test the predictions of the Uπ(6/12)⊗Uν (6/12) supersymmetry scheme in its vibrational limit. The level spectra of3474Se40,3475Se41,3373AS40 and3374As41 supermultiplet nuclei have been calculated using a simple closed energy formula. 44 states in four different nuclei have been reasonably described using only 7 fitted parameters. The existence of supersymmetry was supported also by one-nucleon transfer reaction data, electromagnetic properties, and by a comparison between the supersymmetry and interacting boson-fermion-fermion model wave functions.
