摘要
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 resolution (196)Pe(p,d) and Pt-196((d) over right arrow, t) transfer experiments performed in parallel yielded an improved level scheme of Pt-195. 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 Au-196 using a semimicroscopic transfer operator provides, then, evidence that this description is correct.
