Abstract

The quenching cross sections of ⁴He(2¹S, 2¹P) and ³He(2¹S, 2¹P) states by collisions with Ne (¹S₀) atoms are investigated by a time resolved method. The influence of different processes involved in population or depopulation of these states was evaluated. The quenching cross section for ³He(2¹P) and ³He(2¹S) states by Ne(¹S₀) atoms are σ_2'p = (2.91 ± 0.61)x10^-15cm² and σ_2's = (1.03 ± 0.04)x10^-15 cm² respectively and for ⁴He(2¹P) and ⁴He(2¹S) states - σ_2'p = (1.84 ± 0.45)x10^-15 cm² and σ_2's = (8.62 ± 0.3)x10^-16 cm² respectively.
