Electron Impact Excitation of Extreme Ultra-Violet Transitions in Xe7–Xe10 Ions
In the present work, a detailed study on the electron impact excitation of Xe7+, Xe8+, Xe9+ and Xe10+ ions for the dipole allowed (E1) transitions in the EUV range of 8–19 nm is presented.

Calculation of Rates of 4p–4d Transitions in Ar II
Recent experimental work by Belmonte et al. (2014) has given rates for some 4p–4d transitions that are significantly at variance with the previous experimental work of Rudko and Tang (1967) recommended in the NIST tabulations.

Validation and Implementation of Uncertainty Estimates of Calculated Transition Rates
Uncertainties of calculated transition rates in LS-allowed electric dipole transitions in boron-like O IV and carbon-like Fe XXI are estimated using an approach in which differences in line strengths calculated in length and velocity gauges are utilized.

Cooperative quantum jumps for three dipole-interacting atoms [PDF]
We investigate the effect of the dipole-dipole interaction on the quantum jump statistics of three atoms. This is done for three-level systems in a V configuration and in what may be called a D configuration.
