近阈值（0.5-5.0 eV）的电子-H 2振动激发截面的新的测量和计算挑战以前的决定基于运输分析。在交叉电子-分子束装置中测量的弹性截面和v0 = 0 →v=1截面与用振动密耦理论计算的交换可分离表示的值吻合得很好，特别是在能量低于2.0eV时
New measurements and calculations of near-threshold (0.5-5.0 eV) e-H 2 vibrational-excitation cross sections challenge previous determinations based on transport analysis. Elastic and v 0 =O→v=1 cross sections measured in a crossed electron-molecular-beam apparatus agree well with values calculated using a vibrational close-coupling theory with a separable representation of exchange, particularly at energies below 2.0 eV
