Collisional behavior of Hg{ital X} ({ital B} state) ({ital X}=Cl, Br, I) has been studied during collisions of Ar{sup +}{sub 2} ions with CH{sub 3}Hg{ital X} ({ital X}=Cl, Br, I) molecules in the kinetic energy (lab.) range 100--1000 eV. By using the integrated intensity of the most intense band of the ({ital B}, {ital v}{prime}=0{endash}{ital X}, {ital v}{double prime}=22) transitions in HgCl, HgBr, and HgI at 558, 502, and 443 nm, respectively, emission cross sections were measured at various kinetic energies of the projectile ions. The maximum values of these cross sections for dissociative excitation were found to be 3.8{times}10{sup {minus}19}, 5.7{times}10{sup {minus}19}, and 6.1{times}10{sup {minus}19} cm{sup 2} for HgCl ({ital B}), HgBr ({ital B}), and HgI ({ital B}), respectively.
