Photostop: production of zero-velocity molecules by photodissociation in a molecular beam

Trottier, A.; Carty, D.; Wrede, E.

Abstract

Photostop is an accessible technique capable of producing atoms or molecules at a standstill in the laboratory frame. Starting with a NO2/Xe molecular beam with a mean velocity of 415 m s-1 and a longitudinal translational temperature of 6 K, NO2 molecules are photodissociated to yield NO(X [image omitted]) fragments with a recoil speed equal to the molecular beam speed. The fraction of NO fragments that recoil opposite to the molecular beam are produced with a 6 K longitudinal velocity distribution centred at zero. The NO molecules are allowed to 'evaporate' from the probe volume by waiting for 10
