Radiative parameters of Ho ii and Ho iii levels
Abstract
ABSTRACT Radiative lifetimes of 18 even levels of Ho ii in the energy range between 28692.100 and 44997.566 cm−1 and those of seven levels of Ho iii from 31313.51 to 62804.69 cm−1 were measured by the time-resolved laser-induced fluorescence spectroscopy in laser-induced plasma. To our knowledge, 13 levels of Ho ii and seven levels of Ho iii were measured for the first time. By combining the experimental lifetimes and theoretical branching fractions, the transition probabilities and oscillator strengths for two lines in Ho ii and 30 lines in Ho iii were determined.
