The forbidden transition absorption line positions were found experimentally to be independent of the crystal orientation and this is explained by considering only the nuclear spin-electronic spin interaction term AS. I. However, in order to explain the experimentally observe...
The spectrum of the response function in this relativistic theory contains allowed and forbidden transitions. The computed E1(21,3P1-11S0), M1(23S1-11S0) and M2(23P2-11S0) transition rates agree well with those obtained by refined calculations and with experiment. Accurate values are also ...
Presents the most complete ( n up to 10) set of transitions for FeXIX. Considers both allowed and forbidden transitions. Large number of new energy levels are found. Benchmarks existing accurate energies and transitions. Completeness and accuracy are crucial to solve its abundance in the Sun....

Further, the transition moment arising from the activity of this vibration is shown to be predominantly along the long in‐plane axis in agreement with experiment. The electronically allowed part of the system is stronger than the electronically forbidden part. Detailed consideration of the allowed ...
This has been demonstrated for the 12.25‐V transition by studying its relative intensity as a function of the scattering angle. The data on the 11.86‐V transition are also compatible with an electric quadrupole transition. In addition, new data on the Lyman—Birge—Hopfield bands in the 60–...

The leading-order approximation gives a formulaequivalent to the conventional one and overestimates the decay rate. We demonstrate that thenext-to-leading-order formula reproduces well the exact result for a schematic transition densityas well as a microscopic one obtained by a nuclear energy-...
