Abstract
We report theoretical results for magnetic-field-induced 2p(5)3s 3P(0,2)-2p(6) S-1(0) E1 transitions in Ne-like ions with zero nuclear spin (I = 0) between Mg III and Zn XXI as well as in Ne I. We demonstrate that it is important to include both "perturber" states 2p(5)3s P-1(1) and 2p(5)3s P-3(1) in order to produce reliable transition rates. Furthermore, we investigate the trends of the rates along the isoelectronic sequence of the 2p(5)3s 3P(0,2)-2p(6) S-1(0) transitions and their competition with the 2p(5)3s P-3(0)-2p(5)3s P-3(1) M1 and the 2p(5)3s P-3(2)-2p(6) S-1(0) M2 decays. For the 2p(5)3s P-3(0) state the magnetic-field-induced transition becomes the dominant decay channel for the light elements even in a relatively weak magnetic... (More)

For the 2p(5)3s P-3(0) state the magnetic-field-induced transition becomes the dominant decay channel for the light elements even in a relatively weak magnetic field, and it will therefore prove useful in diagnostics of the strength of magnetic fields in different plasmas. The influence of an external magnetic field on the lifetime of the 2p(5)3s P-3(2) state is much smaller but still observable for the ions near the neutral end of the sequence. As a special case, the magnetic field effect on the lifetimes of 2p(5)3s P-3(0,2) states of neutral Ne-20 is discussed. It is found that the lifetimes are drastically reduced by a magnetic field, which may be an underlying reason for the discrepancies in the lifetime of the 2p(5)3s P-3(2) state between experiment [14.73(14) s] and theory (17.63 s).
