摘要：
A supersymmetry scheme is proposed for nuclear cluster systems. The bosonic sector of the superalgebra describes the relative motion of the clusters, while its fermionic sector is associated with their internal structure. An example of core + alpha configurations is discussed in which the core is a p-shell nucleus and the underlying superalgebra is U(4\12). The a-cluster states of the nuclei Ne-20 and F-19 are analyzed and correlations between their spectra, electric quadrupole transitions, and one-nucleon transfer reactions are interpreted in terms of U(4\12) supersymmetry.
