Abstract

Decay curves of the electric-dipole forbidden decay of the 3s²3p⁴ ground configuration³P₁ level in the S-like ions of Ni ( Z=28) and Cu ( Z=29) have been obtained at a heavy-ion storage ring. This completes the earlier measurements on the ¹D 2 level in Fe^{( Z=26)} and the ¹S 0 level in Ar ( Z=18). The lifetime evaluation process is discussed in the context of structural changes and predicted branching fraction changes along the S I isoelectronic sequence. The experimental lifetime values agree with the results of several calculations.
