Electronic excitation of C4F6isomers by electron impact

Electronic excitation of H2O by low-energy electron impact.

Excitation of electronic states in tetrahydrofuran by electron impact.

We report on differential and integral cross section measurements for the electron impact excitation of the three lowest lying Rydberg bands of electronic states in tetrahydrofuran. The energy range of the present experiments was 15-50 eV with the angular range of the differential cross section measurements being 15°-90°. The important effects of the long-range target dipole moment and the targ...

Vibrational excitation of water by electron impact

Experimental and calculated differential cross sections DCSs for electron-impact excitation of the 010 bending mode and unresolved 100 symmetric and 001 antisymmetric stretching modes of water are presented. Measurements are reported at incident energies of 1–100 eV and scattering angles of 10° –130° and are normalized to the elastic-scattering DCSs for water determined earlier by our group. Th...

Absolute cross sections for electronic excitation of pyrimidine by electron impact.

We measured differential cross sections for electron-impact electronic excitation of pyrimidine, both as a function of electron energy up to 18 eV, and of scattering angle up to 180°. The emphasis of the present work is on recording detailed excitation functions revealing resonances in the excitation process. The differential cross sections were summed to obtain integral cross sections. These a...

Absolute cross sections for electronic excitation of furan by electron impact

We measured differential cross sections for exciting the three lowest electronically excited states in furan, as functions both of electron energy and of scattering angle. Emphasis of the present work is on recording detailed excitation functions, revealing resonances in the excitation process. The cross section for the first triplet state has a shoulder in the first 2 eV above threshold, assig...
