Lithium reactions: Relative angular and speed cross sections from crossed beam collisions

A new crossed beam technique was developed which combines magnetic deflection and velocity analysis to look at the products from reactions of lithium atoms with halogen containing molecules. An inhomogeneous magnetic field deflected by the nonreacted species before a hot tungsten surface was used to ionize undeflected product species. This detection method in combination with velocity analysis of the products at a wide range of scattering angles determined the dependence of the cross section on recoil angle and speed for a number of Li reactions. This technique was used to study the reactions of Li with No2, Cl2, Br2, ICl, CH3I, CH3NO2, (CH)2CHNO2, CCl4, SnCl4, PCl3, and SF6.
