Va. Astapenko, STIMULATED BREMSSTRAHLUNG INVOLVING MULTIPLY-CHARGED IONS IN A STRONGLASER FIELD - POLIARIZATION-INTERFERENCE EFFECTS FOR NEAR-RESONANCE FREQUENCIES WITH ALLOWANCE FOR FINE SPLITTING, Laser physics, 8(5), 1998, pp. 1066-1069
Approximation of a fixed current is employed to calculate the cross se
ction of stimulated bremsstrahlung of quasi-classical electrons due to
multiply charged ions with allowance for dynamic polarization of the
ionic core by a laser field and interference of static and polarizatio
n channels. The main attention is focused on transitions that do not c
hange the principal quantum number Such transitions can be considered
within the framework of the dipole approximation in the interaction of
an incident particle and the electronic core. The influence of the fi
ne splitting of a near-resonance transition and the broadening effect
of the laser field on the spectral dependence of the process under stu
dy are analyzed.
