Dynamical Supersymmetries in Nuclei

It is suggested that dynamical (Bose-Fermi) supersymmetries may be present in the spectra of complex nuclei. A concrete example in which a supersymmetric structure is experimentally observed is shown. In this example the supersymmetry is generated by $L=0$ and $L=2$ bosons together with $j=\frac{3}{2}$ fermions.
