英文摘要: A high resolution study of the high-n Rydberg H atom scattering with helium was carried out using the H atom Rydberg tagging time-of-flight technique. Differential cross sections were measured for scattering process of H (n) + He -> H (n') + He at the collision energy of 0. 526 eV. Experimental result indicates that the scattered H (n') product is mainly forward distributed, with signals observed in the wide range of angles at the sideway and forward scattering directions. At the sideway and forward directions, a lot of oscillatory structures in the angular distributions are present. Detailed analysis also shows that the principle quantum number, n, is not changed much for the Rydberg H atom at the forward scattering direction. This work provides a good test ground to investigate theoretically the exact collision dynamics between the high-n Rydberg H atom and the helium atom.
