Journal ArticleDOI
Exact Quantum-Mechanical Calculation of a Collinear Collision of a Particle with a Harmonic Oscillator
Don Secrest,B. Robert Johnson +1 more
TL;DR: In this article, a semi-empirical formula for computing quantum-mechanical transition probabilities for collinear collision of an atom with a diatomic molecule is given.
Journal ArticleDOI
Theory of angular momentum decoupling approximations for rotational transitions in scattering
TL;DR: In this paper, a systematic method is discussed for decoupling the internal angular momentum of molecules involved in a collision from their relative angular momentum, which leads to a large class of rotational approximations of varying degrees of complexity and accuracy.
Journal ArticleDOI
Helium-atom--hydrogen-molecule potential surface employing the lcao--mo-- scf and ci methods.
Michael David Gordon,Don Secrest +1 more
TL;DR: In this paper, the wavefunctions and interaction energies for the helium-atom-hydrogen-molecule system at a wide range of internuclear separations are calculated.
Journal ArticleDOI
Calculation of Rotational and Vibrational Transitions for the Collision of an Atom with a Rotating Vibrating Diatomic Oscillator
Walter Eastes,Don Secrest +1 more
TL;DR: In this paper, a practical method for computing the T-matrix elements for a rotating, vibrating oscillator is presented. But the method is not suitable for the case of rotational transitions from the ground to the first accessible excited rotational state.
Journal ArticleDOI
The generalized log‐derivative method for inelastic and reactive collisionsa)
F. Mrugal,Don Secrest +1 more
TL;DR: In this paper, a generalized version of the log-derivative method for both reactive and non-reactive scattering problems is presented, where a first derivative term is included for complete generality.
