SEMICLASSICAL COUPLED WAVEPACKET STUDY OF THE CHARGE-TRANSFER REACTION AR++O2 (X(3)SIGMA(G)(-))][--]AR+O2+(A(4)PI(U))

This paper presents a preliminary study of the title reactions in the energy range 0.6 to 4 keV. Because of the lack of available data, a series of assumptions based on asymptotic considerations have been made to guess reasonable potential energy surfaces. Moreover, as in this system the expansion of the nuclear wavefunction over a basis set leads to an intractable system of coupled differential equations, the semiclassical dynamical treatment is based upon a coupled wavepacket method. Except in one situation where a strong discrepancy is observed, we obtain a qualitative agreement with most of the experimental data.
