Abstract
Electron-impact excitation cross sections are calculated and presented for the dipole-and spin-allowed transitions from the ground states to the np 2P states for hydrogen and lithium, and to the 1snp 1P states for helium, n=2 through 10. Two scaling formulas developed earlier by Kim [Phys. Rev. A 64, 032713 (2001) for plane-wave Born cross sections are used. The scaled Born cross sections are in excellent agreement with available theoretical and experimental data.Citation
