Structural relaxation dynamics of electronically excited XeArN clusters
In this article we explore the structural, dynamic, and spectroscopic implications of large local configurational changes in electronically excited Xe*ArN (N=12,54,146,199) heteroclusters, where the X...

Spin-restricted open-shell coupled-cluster theory
Spin-restricted CC theory is suggested as a new approach for the treatment of high-spin open-shell systems in CC theory. Spin constraints are imposed on the wave function in the sense that the project...

We describe light emission from the complex formed during ion–atom collisions, that arises from electronic charge transfer and the related oscillatory dipole of the complex. This is treated in an eikonal/time-dependent Hartree–Fock approach which accounts for coupling of electronic and nuclear motions and generates the time-dependent dipole of the complex. Calculations were done for H++H with a basis set of travelling atomic functions, for collision energies of 100, 250, and 1000 eV, to obtain the energy emitted per solid angle versus both time and the light frequency. Results are presented for the intensity components of the light emitted parallel and perpendicular to the incoming projectile H+ velocity. Light emission is found to last several femtoseconds, and to be distributed over ultraviolet frequencies. The intensity of light emitted by the complex H<sub>2</sub><sup> + </sup> increases as collision energies are lowered. ©1997 American Institute of Physics.
