Status of the DR Project Level-resolved DR rate coefficients for H-like through Mg-like isoelectronic sequences have been computed. The state-of-the-art AUTOSTRUCTURE package has been used. For each sequence, calculations were performed up to Zn and we included other heavy ions such as Kr, Mo, and Xe.

DR Rate Coefficient for S3+ At low T, the contributions from 3s23pnl core relaxation is forbidden in LS-coupling. Why DR for IC-coupling is reduced? 1/2/2019

3s → 3p excitation n=36 IC The reduction in the DR occurs at n=36 for both 3s3p2(2P1/2, 3/2)nℓ which is reflected in DR. Such reduction doesn’t exist in LS coupling 3s3p2 2Pnℓ LS FWHM=1.2 meV 1/2/2019
