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
Quantum‐Mechanical Calculations of the Inelastic Cross Sections for Rotational Excitation of Para and Ortho H2 upon Collision with He
B. Robert Johnson,Don Secrest +1 more
TL;DR: In this article, the authors derived the equations for computing the scattering T matrix in the total-angular-momentum representation and showed that in the appropriate limit this method reduces to a first-order differential equation for the T matrix.
Journal ArticleDOI
The Solution of the Nonrelativistic Quantum Scattering Problem without Exchange
B. Robert Johnson,Don Secrest +1 more
TL;DR: In this article, the authors proposed a method of "amplitude density functions" which allows a scattering problem to be broken up into problems with weaker interaction potentials, and these simpler problems may be solved separately and then added together to give the total solution.
