摘要：

The cross section for the electron-impact excitation of the hydrogen atom to the 2p radiative state has been measured from the threshold (at 10.2 eV) to 50 eV. Primary interest is given to the region between the threshold and the n=4 level of the hydrogen atom, where several resonances have been identified. An electron-beam resolution of 0.07 eV has been used to study the resonances, while a resolution of 0.18 eV has been used to determine the general behavior of the cross section. Below n=3 the S1 resonances appear to agree with the theoretical predictions, but in the case of the higher angular-momentum D1 resonance, the agreement between present theory and experiment is poor. Balmer-α excitation is discussed. © 1969 The American Physical Society.
