Ai. Pegarkov, Intense interactions of molecules with a short-wavelength electromagnetic radiation field: I. The fundamentals of the nonadiabatic theory, OPT SPECTRO, 91(1), 2001, pp. 82-86
The intense interactions between short-wavelength (SW) electromagnetic radi
ation with a wavelength lambda greater than or equal to 1 Angstrom and inte
nsity up to 10(14) W/cm(2) and simple and polyatomic molecules are studied
with the coherent excitations of high-lying Rydberg and autoionizing states
taken into account. The Hamiltonian of a system "molecule + SW radiation"
is obtained by using the methods of quantum electrodynamics. Conditions for
the applicability of the dipole approximation to describe the interactions
of molecules with radiation of the UV, VUV, XUV, and soft X-ray range are
found. The fundamentals of the theory of resonance scattering of SW radiati
on from diatomic, triatomic, and symmetric- and asymmetric-top polyatomic m
olecules are outlined. (C) 2001 MAIK "Nauka/Interperiodica".
