Evidence for the Existence of Supersymmetry in Atomic Nuclei

We found strong evidence for the existence of supersymmetry by studying the odd-odd nucleus ¹⁹⁶Au using the ¹⁹⁷Au(d⃗,t), ¹⁹⁷Au(p,d), and ¹⁹⁸Hg(d⃗,α) transfer reactions. High resolution ¹⁹⁶Pt(p,d) and ¹⁹⁶Pt(d⃗,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.
