SUMMARY
Diatomic helium molecules (He2) can be formed under specific conditions, primarily through ionizing radiation, which can produce He2+ ions and electronically excited states (He2*). However, He2 is only stable as a van der Waals molecule at very low temperatures, existing in molecular beams with a weak bond and significant interatomic spacing. The formation of He2 requires careful control of environmental conditions, particularly in condensed phases or during specific expansions like the Joule-Thomson (JT) effect.
