Atomic Alignment Effect on the Branching to ArCl* and CCl2* Formation in the Reaction of Oriented Ar(P-3(2),M-J=2) + CCl4
Atomic alignment effects for the formation of ArCl*(C) and CCl2*((A) over tilde) in the reaction of Ar(P-3(2)) + CCl4 have been measured by using an oriented Ar((P2,MJ)-P-3=2) beam at a collision energy of 0.08 eV. The emission intensity for ArCl*(C) and CCl2*((A) over tilde) has been measured as a function of the magnetic orientation field direction in the collision frame. A significant atomic alignment effect is observed for the atom transfer process [ArCl*(C) formation]. Formation of ArCl*(C) is modestly enhanced when the electron angular momentum of the Ar(P-3(2)) reactant is aligned along the relative velocity vector. while the excitation transfer process [CCl2*((A) over tilde) formation] shows little alignment effect.
