Semiclassical Study Of The Vibrational Excitation Of H2 In Collision With He, Gordon W. F. Drake, C. S. Lin

Physics Publications

The vibrational excitation and dissociation probabilities of H2 in a collinear collision with He are calculated, using the semi-classical time-dependent method along with the accurate H2 molecular potential of Kolos and Wolniewicz (1965, 1968). The complete set of bound and continuum eigenfunctions are represented in terms of a truncated basis set of harmonic oscillator functions. The results differ significantly from the Morse potential quantum mechanical calculations of Clark and Dickinson (1973). In addition, a state-dependent interaction potential is suggested to allow for the different average sizes of the H2 molecule in its initial and final states. The state dependent potential …


Leading Radiative Correction To The Magnetic Dipole Transition Probability, Gordon W. F. Drake Jan 1974

Leading Radiative Correction To The Magnetic Dipole Transition Probability, Gordon W. F. Drake

Physics Publications

It has recently been suggested that a radiative correction of relative order ln may contribute to the 1s2sS13-1s2S01 magnetic dipole transition of the heliumlike ions. The low-frequency contributions to the correction are evaluated and shown to vanish. © 1974 The American Physical Society.
