Abstract:

A general formalism to treat radiative emission of a colliding three-particle system is developed in the semiclassical approximation. The matrix element of the matter-radiation interaction is separated into three terms representing the center of mass, the intersystem bremsstrahlung, and the electron bremsstrahlung. At each step we impose the off-shell orthogonality property of the mechanical wave functions. Instead of internuclear bremsstrahlung, used so far, a more general concept of intersystem bremsstrahlung is introduced. The electron bremsstrahlung is calculated using eikonal distorted wave functions, and good agreement is found with experiment. Radiative electron excitation and deexcitation have also been calculated. The former is found to be very small, while the spectrum associated with the latter produces the continuous emission around the characteristic line, induced by the passing projectile. © 1986 The American Physical Society.

  • It can be easily shown that a first perturbative order of the Nordsieck's closed form gives the Bethe's expression Eq. (77.3) of Ref. 21. Note that this expression is for any kind of potential, while the Nordsieck one is only for pure Coulomb interaction; Closed forms for the integrals of Eqs.
