QCT Study on the Reaction Scattering of Na₂（X~¹∑_g⁺）+Cl（3²p）

The reaction channel Cl（3²p）+Na₂（X¹∑_g⁺）→Na（3²s）+NaCl（X¹∑） was studied with the Quasiclassical Trajectory method （QCT）. It was found that initial collision energy plays an important role in the reaction. Total reaction cross sections decrease rapidly as E_col increases. The result of calculation implies a direct process at low collision energy and the existance of a collisional complex at high collision energy. The product NaCl was found to distribute on its vibration-rotation energy level broadly.
