The rate constants for collisionally induced transitions between Zeeman levels in ground-state oxygen have large magnitudes in a 1 T field. It is shown that magnetic fields induce the forbidden P-3(1) --> P-3(0) transition in ultracold collisions of carbon with helium. The cross section vanishes at zero energy for field-free collisions, but becomes infinitely large in a finite magnetic field, varying with velocity v and magnetic field B as B-2/v. dc.language.iso en_US dc.publisher American Physical Society dash.license LAA dc.title Disalignment transitions in cold collisions of 3 P atoms with structureless targets in a magnetic field dc.type Journal Article dc.description.version Version of Record dc.relation.journal Physical Review A - Atomic, Molecular, and Optical Physics dash.depositing.author Dalgarno, Alexander::501fae4cfad8b04754ee2838c45fc5d0::600 dc.date.available 2019-09-27T13:20:30Z dash.workflow.comments 1Science Serial ID 75883 dc.identifier.doi 10.1103/PhysRevA.68.013406 dash.source.volume 68;1
