Radiative attachment of a positron to atomic helium in the triplet state
- College of Notre Dame of Maryland, Baltimore, Maryland 21210 (United States)
In this study we evaluate the cross section for forming the nonrelativistically bound state of a positron with the helium triplet atom by radiative attachment. Although this cross-section was expected to be small compared with a competing rearrangement process involving positronium and ground-state helium, this calculation is a first step which should be useful for experimental production of this interesting system.
