Atomic Transition Probabilities for UV and Optical Lines of Gd ii

We report new branching fraction (BF) measurements for 156 ultraviolet and optical transitions of Gd ii . These transitions range in wavelength (wavenumber) from 2574 to 6766 Å (38,838–14,777 cm ^−1 ) and originate in one odd-parity and 11 even-parity upper levels. Nine of the 12 levels, accounting...
