摘要：

Experimental and theoretical differential cross sections (DCS) for the electron-impact excitation of molecular hydrogen to the B (1)Sigma(+)(u), c (3)Pi(u), a (3)Sigma(+)(g), C (1)Pi(u), and the E(F) (1)Sigma(+)(g) states are presented at incident energies near to threshold. The experimental DCSs were taken at incident energies of 14, 15, 16 and 17.5 eV and for scattering angles from 10 degrees to 130 degrees. The theoretical DCSs are from the convergent close-coupling method which has recently successfully modeled differential electron scattering from H-2 when compared with available experiment at energies of 17.5 eV and above.
