Abstract
We found strong evidence for the existence of supersymmetry by studying the odd-odd nucleus Au-196 using the Au-197((d) over right arrow, t), Au-197(p , d), and Hg-198((d) over right arrow, alpha) transfer reactions. High reso lution (196)Pe(p,d) and Pt-196((d) over right arrow, t) transfer experiment s performed in parallel yielded an improved level scheme of Pt-195. Using e xtended supersymmetry, a single fit of the six parameter eigenvalue express ion 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 Au-196 usi ng a semimicroscopic transfer operator provides, then, evidence that this d escription is correct.
