The α-cluster states of20Ne,19Ne and18Ne have been analyzed as members of a supermultiplet predicted by the U(4|12) cluster supersymmetry scheme. The analysis of B(E2) data and one-nucleon transfer reactions seem to support the validity of this scheme. The α-cluster states of the22Ne nucleus have been analyzed independently, and were compared with DAMD and GCM calculations. Based on these results, a similar study of21Ne seems worthwhile.
