Theory of the angular distribution of 2p? molecular orbital X-rays

Abstract

The cross section and anisotropy of 2pa 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 2pa molecular-orbital X-ray anisotropy is in good agreement with experiment. When one includes the Coriolis coupling between the 2pa and 2pTr and between the 3da, 3dn, and 3d5 molecular orbitals, the 2pa-line-tail intensity is greatly reduced below that calculated by J~iger et al., neglecting the Coriolis coupling. The implications of these calculations to the possible spectroscopy of superheavy quasimolecules are discussed, andsome suggestions aremade to improve the accuracy of the spectroscopy measurements.
