Low-energy (O-5 V above threshold) electron-impact excitation spectra and a trarismission spectrum are presented for acetylene. it is found that excitation via temporary negative ions plays a domimnt role. Assignments are suggested for the observed electronic excitation processes.
Intense smglet-triplet transihons are observed for saturated hydrocarbons when they are excited by impact of low-energy (5-15 eV) electrons. Excitation spectra are presented for methane, ethane, cyclopropane, and cyclooctane.
We present numerical results for He (1s 2 ) (e, 2e) He + reaction process for transitions to the n = 1, 2 and 3 states of He + for noncoplanar symmetric geometry at incident energies of 1000 and 1600 eV. The calculations are performed using the plane wave impulse approximation (PWIA) and the 3C meth
