Hyperfine-state-dependent lifetimes along the Ni-like isoelectronic sequence

Andersson, M. ; Yao, K. ; Hutton, R. ; Zou, Y. ; Chen, C. Y. and Brage, Tomas LU (2008) In Physical Review A (Atomic, Molecular and Optical Physics) 77(4). p.12-042509
Abstract
An investigation of the lifetime of the 3d(9)4s D-3(3) level along a part of the nickel-like isoelectronic sequence has been performed. The focus of this work has been to evaluate the importance of the hyperfine induced electric quadrupole channel of the 3d(10) S-1(0)-3d(9)4s D-3(3) transition for isotopes with nuclear spin. Comparisons between the magnetic octupole transition rate and the hyperfine-induced electric quadrupole transition rate shows that the hyperfine quenching is of importance along the whole isoelectronic sequence. At the low-Z end the hyperfine induced electric quadrupole transition channel dominates, being several orders of magnitude larger than the rate for the magnetic octupole transition channel, while for higher Z...
