Description

The asymmetry parameter β for the O K shell photoemission of the CO molecule has been measured for different vibrational states of the residual ion. The corresponding calculations performed by us in the relaxed core Hartree-Fock approximation are in qualitative agreement with the experiment. From the analysis of theoretical data, we made the conclusion that the variation of β with the vibrational quantum number is connected with different dependences of the dipole matrix elements in the sσ, dσ, and fσ channels on the internuclear distance R in the σ* shape resonance
