Quasimolecular bremsstrahlung in heavy-ion collisions

In heavy-ion collisions, the molecular electronic dipole moment is accelerated and may emit continuum x rays even in the absence of inner-shell vacancies. Semiclassical calculations of the bremsstrahlung intensity are made for 200-MeV Kr + Ti encounters using hydrogenic two-center wave functions to calculate the molecular dipole moment. The bremsstrahlung is confined to x-ray energies below the Kr $K$ x-ray lines.
