| dc.description | Helium at pressures ranging from 0.5 to 8 bar is excited by an intense e-beam. The absolute population densities of the He(2 <sup>1</sup>P), He(2 <sup>3</sup>P) and He<sub>2</sub><sup>*</sup>(a,v), v=0, 1, 2 states are determined by measuring the transient absorption of probe light delivered by a dye laser. The experimental data are readily described by a kinetic model taking into account the excitation and the de-excitation processes. The recombination of He<sub>2</sub><sup>+</sup> by a termolecular reaction with e+He to He(2 <sup>3</sup>P) as proposed by Bates (1984) is confirmed quantitatively. The rate constants for the termolecular reactions of He(2 <sup>1</sup>P) and He(2 <sup>3</sup>P) were deduced to be (1.8+or-0.4)*10<sup>-31</sup> cm<sup>6</sup> s<sup>-1</sup> and (1.6+or-0.4)*10<sup>-32</sup> cm<sup>6</sup> s<sup>-1</sup> respectively. The rotational and vibrational relaxation of He<sub>2</sub>(a) by helium is investigated. |
