SAC-CI general-R study of the ionization spectrum of HCl
The valence ionization spectrum of HCl is studied by symmetry-adapted-cluster configuration-interaction general-R and SD-R methods. The general-R method describes well the peak positions and intensities of seven satellite lines observed below the double ionization threshold. The twinning shake-up states due to the (4σ)−1 state and the Rydberg states of HCl+ are correctly reproduced.
