“…Such a dependence was first proposed by Meyerhof et al (1974) and criticized by Thorson and Choi (1977). Nevertheless, reasonable agreement between theory and experiment is obtained, and the Several other measurements of K MO x-ray production probabilities have been made (Tserruya et al, 1976;Schuch et al, 1980;Stiebing et al, 1984). In 143-MeV Nb -f Nb collisions, Schuch et al (1980) found that the impact-parameter dependence of 2pa MO x-ray production follows that of AT-vacancy production, as suggested by Anholt and Meyerhof (1977).…”

In slow heavy-ion-atom collisions, inner-shell electrons with velocities larger than the projectile velocity form diatomic molecular orbitals around the projectile and target nuclei. If a vacancy exists in one of these orbitals, it can decay at some point during collision, emitting an x ray characteristic of the molecular transition energy at that internuclear distance. Since the projectile-target internuclear distance varies during the collision, x-ray continua are seen, which for \so molecular-orbital x rays (transitions to vacancies in the lowest Iscr orbital) stretch toward the united-atom AT-shell binding energy. This paper reviews the theory of and the experimental evidence for molecular-orbital x-ray emission. A historical overview of the development of these studies is given, showing how the theory of quasimolecular x-ray emission has evolved from a semiclassical quasistatic model to a general dynamic theory, including the Coriolis coupling between molecular orbitals making up the initial and final states. X-ray cross section, angular distribution, and other measurements are discussed, and their impact on the development of the theory of molecularorbital x-ray emission is illustrated.
