Atomic alignment effects for the formation of excimers, RgX* (B, Omega = 1/2) and RgX* (C, Omega = 3/2), in the reaction of Rg (P-3(2)) (Rg = Xe, Kr, Ar) with halogen (X)-containing molecules (RX) (CH3I, CF3I, CF3Br, NF3, CHBr3, CHCl3, CCl3F, and CCl4) have been measured by using an oriented Rg (P-3(2), M-J = 2) atomic beam at a collision energy of similar to 0.07 eV. The emission intensities for RgX* (B, C) have been measured as a function of the magnetic orientation field direction in the collision frame. The reactant (RX) dependence of the atomic alignment effect is extremely different between the RgX* (B) and the RgX* (C) channels. For RgX* (C), an analogous atomic alignment effect is commonly observed despite the difference of RX and Rg. In contrast, for RgX* (B), the atomic alignment effect shows a diverse dependence on RX and Rg.
