| Abstract: | The rate coefficient for deactivation of the metastable 23S state of He by impact of thermal electrons is deduced from recent calculations of inelastic electron-He cross sections. The deactivation rate is found to be nearly constant with temperature. Computed values range between 2.82 and 3.03 (10?9 cm3/sec) for T between 0 and 2000°K. De-excitation cross sections are given for low-energy incident electrons. |
