Under single-collision beam-gas scattering conditions the reactions Ba+ C_2H, Br、n-C_3H_7Br、1, 2-C_2H_4Br_2、1,3-C_3H_6Br_2 have been studied using laser induced fluore-scence to detect the BaBr X~2∑~+ product. The vibrational distributions, the fractions of the available energy ing into vibrational and rotational energy of the BaBr products have been calculated by means. of computer simulation. It has been found that the average vibrationel energies of the BaBr products can be described as a linear function of the mass factors for the reactions Ba+CH_3Br、C_2H_5Br、n-C_3H_7Br、1,3-C_3H_6Br, and that the potential energy surfaces for these reactions are similar. For the reactions Ba+CH_3Br、C_2H_5Br、n-C_3H_7Br, the vibrational increae, but for the reactions Ba+CH_2Br_2、1,2-C_2H_4Br_2、1,3-C_3H_6Br_2, the vibrational excitations of the BaBr products decrease greatly when the number of the carbons increase.
