我们报告了在 Nd:YAG 激光器发出的 1.17 eV 光子存在的情况下，氦原子对电子散射的测量。电子的入射能量在50-350 eV范围内，并且激光的偏振被布置为平行于135度散射的电子。观察到对应于一光子和双光子发射的能量转移峰。使用 Kroll-Watson 近似的计算与数据完全一致。
We report measurements of the scattering of electrons by helium atoms in the presence of 1.17 eV photons from a Nd:YAG laser. The incident energy of the electrons was in the range 50-350 eV, and the polarization of the laser was arranged to be parallel to electrons scattered through 135 deg. Energy-shifted peaks corresponding both to one- and two-photon emission were observed. Calculations using the Kroll-Watson approximation are perfectly consistent with the data.
