Abstract

We found strong evidence for the existence of supersymmetry by studying the odd-odd nucleus 196Au using the 197Au(d,t), 197Au(p,d), and 198Hg(d,α) transfer reactions. High resolution 196Pt(p,d) and 196Pt(d,t) transfer experiments performed in parallel yielded an improved level scheme of 195Pt. Using extended supersymmetry, a single fit of the six parameter eigenvalue expression yielded a complete description of all observed low-lying excited states in the four nuclei forming the supermultiplet. The detailed comparison of the transfer amplitudes the odd-odd member of the supermultiplet 196Au using a semimicroscopic transfer operator provides, then, evidence that this description is correct.
