摘要：

By means of a numerical analysis of the 2+ doublet in Be-8, we show that accidental degeneracies of two resonant states mixed by a Hermitian interaction are associated with the occurrence of a simple and a double pole of the S-matrix in the complex energy plane. A true crossing may be brought about by the variation of just two parameters.
