The collision cross section for ion-molecule reactions at low energies is predicted by the Langevin-Gioumousis-Stevenson (LGS) model (Gioumousis and Stevenson, 1958),... [Pg.192]

This is known as the Langevin-Gioumousis-Stevenson form ofthe reaction cross-section. It impUes that the reaction rate constant va r is (nearly) independent of the collision energy so that the thermal reaction rate constant is nearly independent of temperature. [Pg.92]
