Improved Theoretical Spectrum of Quasibound States and Resonances for H2(1∑g+)

Abstract

AbstractThe most recent ab initio potentials for H2(1∑g+), which include relativistic, adiabatic and radiative corrections, were used to calculate the spectrum of quasibound states. The levels, widths and tunneling permeability of resonant states were also studied by the quantum phase‐shift method. A new set of relevant resonance states for the calculations of atomic recombination of hydrogen is indicated by the present work. In comparison with the previous studies, significant improvements have been found for the resonances.
