Decay curves of the electric-dipole forbidden decay of the
ground configuration 3P1 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 1D2 level in Fe (Z=26)
and the 1S0 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.
