The metastable fraction of the 2S state that slows down below the 2P threshold without undergoing collisional quenching has been calculated as a function of the initial kinetic energy using a Monte Carlo kinetics program. Contrary to earlier estimates, the metastable fraction in the kinetic energy range of 2-5 eV cannot be neglected.14 pages, 8 figuresNuclear Theorytext
