Abstract
The cross section and anisotropy of 2pσ molecular-orbital X-ray emission is calculated for 35- to 75-MeV Nb + Nb collisions. The calculated intensities are a factor of 1.5 lower than the measured ones. The 2pσ molecular-orbital X-ray anisotropy is in good agreement with experiment. When one includes the Coriolis coupling between the 2pσ and 2pπ and between the 3dσ, 3dπ, and 3dδ molecular orbitals, the 2pσ-line-tail intensity is greatly reduced below that calculated by Jäger et al., neglecting the Coriolis coupling. The implications of these calculations to the possible spectroscopy of superheavy quasi-molecules are discussed, and some suggestions are made to improve the accuracy of the spectroscopy measurements.
