Abstract:
Non-orthogonal orbitals technique in the multiconfiguration
Hartree-Fock approach is used to calculate oscillator strengths and
transition probabilities for allowed and intercombination lines in Cl
II. The relativistic corrections are included through the Breit-Pauli
Hamiltonian. The Cl II wave functions show strong term dependence. The
non-orthogonal orbitals are used to describe the term dependence of
radial functions. Large sets of spectroscopic and correlation
functions are chosen to describe adequately strong interactions in the
3s2 3p3nl 3Po, 1Po and 3Do Rydberg series and to
properly account for the important correlation and relaxation effects.
The length and velocity forms of oscillator strength show good
agreement for most transitions.
