【摘要】 本工作利用分子束装置,研究了Ba+N₂O化学发光反应截面σ_?与碰撞能E的关系。得全在相对平动能0.1～0.3eV时σ_?≌0.1（?）²。在束一气装置上得到碰撞总截面σ₁₀₁～92（?）,并利用Arrhenius实验曲线给出在T_N2O～300K时活化能E_α^*=1.0千卡/克分子,从而得出,:奖发态的产物粒子仅是总碰撞数的千分之一更多还原

【Abstract】 This Work studied reactant’s beam (gas) intensity (Concentration) dependence of the chemiluminesccnt intensity, Collision energy E dependence of the chemilunlinescent cross section σcl, and σcl= 0.1A2 at range of the relative translational energies 0~0.3eV were obtained for Ba+N2O reaction. The total cross section σ =92+++10A2 was obtained with abeam gas apparatus. The experimental activation energy E =1.0kcal/mole was obtained from an Arrhenius experimental curve at room temperatureT_N2O.更多还原
