Complex-Coordinate Coupled-Channel Methods for Predissociating Resonances in van der Waals Molecules... [Pg.263]

Complex-Coordinate Coupled-Channel (CCCC) methods are presented for the accurate and efficient treatment of the resonance energies and widths (lifetimes) of multichannel rotatlonally predissociating van der Waals (vdW) molecule resonances. Algorithms for dealing with the complex scaling of numerical and piecewise analytical potentials are also presented. [Pg.263]

Hamiltonian and Complex-Coordinate Coupled-Channel Formulation In Space-Fixed Coordinates (18-21). The hamlltonian of a trlatomlc vdW molecule A...BC, after separating out the motion of the centre of mass, may be expressed In the SF frame as... [Pg.266]

We now discuss the complex-coordinate coupled-channel (CCCC) formulation in the SF frame. According to the theory of complex-coordinate transformation, the energy (Ej ) and the width (F) associated with a metastable state of the vdW molecule may be determined by the solutlo of the complex eigenvalue of a non-hermitian ham-11 tonlan H (Re, r), obtained by applying the complex-coordinate...

The complex-coordinate coupled-channel (CCCC) formulations described In the last section have been applied to the determination of resonance energies and widths (lifetimes) of several rotatlonally pre-dlssoclatlng vdW molecules, including Ar-H2 (19), Ar-HD (20),... [Pg.272]
