Relativistic coupled cluster calculations on hyperfine structures and electromagnetic transition amplitudes of In III
Abstract
Hyperfine constants and anomalies of ground as well as few low lying excited states of In III are studied with highly correlated relativistic coupled-cluster theory. The ground state hyperfine splitting of In III is estimated to be 106.8 GHz. A shift of almost 1.9 GHz of the above frequency has been calculated due to modified nuclear dipole moment. This splitting result shows its applicability as communication band and frequency standards at sec. Correlations study of hyperfine constants indicates a few distinct features of many-body effects in the wave-functions in and near the nuclear region of this ion. Astrophysically important forbidden transition amplitudes are estimated for the first time in the literature to our knowledge. The calculated oscillator strengths of few allowed transitions are compared with recent experimental and theoretical results wherever available.
