Let g= g 0¯⊕ g 1¯ be a basic classical Lie superalgebra over C, e∈ g 0¯ a nilpotent element and g e the centralizer of e in g. We study various properties of nilpotent elements in g, which have previously only been considered in the case of Lie algebras. In particular, we prove that e is reachable if and only if e satisfies the Panyushev property for g= sl (m| n), m≠ n or psl (n| n) and osp (m| 2 n). For exceptional Lie superalgebras g= D (2, 1; α), G (3), F (4), we give the classification of e which are reachable, strongly reachable or satisfy the Panyushev property. In addition, we give bases for g e and its centre z (g e) for g= psl (n| n), which completes results of Han on the relationship between dim g e, dim z (g e) and the labelled Dynkin diagrams for all basic classical Lie superalgebras.
