Comment on "Photoelectron spectroscopic studies of polyatomic molecules: Theory for spin polarization"

The relation between the theory developed recently by Chandra [Phys. Rev. A 40, 752 (1989)] and our theory, derived previously [N. A. Cherepkov, J. Phys. B 16, 1543 (1983); 14, 2165 (1981); Adv. At. Mol. Phys. 19, 395 (1983); N. A. Cherepkov and V. V. Kuznetsov, Z. Phys. D 7, 271 (1987)], is established.
