ABSTRACT
We found strong evidence for the existence of supersymmetry by studying the odd-odd nucleus [sup 196]Au using the [sup 197]Au(dvector ,t), [sup 197]Au(p,d) and [sup 198]Hg(dvector ,α) transfer reactions. High resolution [sup 196]Pt(p,d)[sup 195]Pt and [sup 196]Pt(dvector ,t)[sup 195]Pt transfer experiments performed in parallel yielded at the same time an improved level scheme of [sup 195]Pt. 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 different nuclei forming the supermultiplet. The detailed comparison of the transfer amplitudes for the states up to 500 keV in the odd-odd member of the supermultiplet [sup 196]Au using a semi-microscopic transfer operator provides then evidence that this description is correct. © 2000 American Institute of Physics.
