WebHyperfine mixing of LS -coupled atomic states can open new radiative decay channels for processes that would normally be strongly suppressed. For example, spin-forbidden processes may become enhanced. We study the lifetimes of the hyperfine levels of the two-electron isotopes 8 B (I = 2) and 11 B (I = 3 / 2) in connection with nuclear charge radius … WebThis originates from strong hyperfine mixing between singlet and triplet states. The hyperfine structure of 3He with an external magnetic field is precisely calculated by using double basis set wave functions. The comparison with available experiments effectively tests the theory of hyperfine structure.

WebThe hyperfine structure of a large number of transitions in Al II cannot be described using A and B hyperfine constants and the hyperfine structure is therefore said to be anomalous. In this paper, we have studied the hyperfine structure of a few transitions in Al II, 3s5s(3)S-3s5p(3)P, 3s4d(3)D-3s5p(3)P and 3s5p(3)P-3s5d(3)D, by combining theory and … Webapproach degeneracy and are susceptible to hyperfine mixing, which reduces P S (light blue area of Fig. 2B). When B < B nuc all three degenerate triplet states can mix with S at large detuning, which further reduces P S compared to the finite field case.
