“…where κ n is a constant, which comprises the eigenvalues. Then, the energy eigenvalues are obtained from [23] [49,50,51,43,52,53,54,55,56,57,58,44,59,60,61] for the ground state bandhead R 0,0,4 ratios, as well as those of the β and γ bandheads, normalized to the 2 + g state and labelled by R 1,0,0 and R 0,2,2 , respectively. L g , L β and L γ characterized the angular momenta of the highest levels of the ground state, β and γ bands, respectively, included in the fit.…”
