SOME THEORETICAL ASPECTS OF THE GROUP-IIIA-ION ATOMIC CLOCKS - INTERCOMBINATION TRANSITION-PROBABILITIES

The main focus of this paper is the theoretical study of the 3P11S0 intercombination transition probabilities of the group-IIIA ions that are excellent candidates for high-accuracy atomic clocks. The importance of relativistic effects on the intercombination transition probabilities is made apparent by comparing their calculated values with those of the allowed 1P11S0 transition probabilities. In striking contrast to the allowed transition probabilities, the intercombination transition probabilities exhibit a strong Z dependence. © 1990 The American Physical Society.
