Physical review letters, 2009•APSThe cross sections for the formation of positronium in the 2 P state in collisions of positrons
with He, Ar, and Xe atoms have been determined by measuring coincidences between the
remnant ion and the Lyman-α photon from positronium. The maximum fractional
contributions of these to the total Ps formation cross sections increase from approximately
0.06±0.01 in He to 0.12±0.04 in Ar and 0.26±0.09 in Xe. In the case of He, good agreement
is found with a coupled-state calculation; for Ar and Xe, measurements are compared with a …

The cross sections for the formation of positronium in the state in collisions of positrons with He, Ar, and Xe atoms have been determined by measuring coincidences between the remnant ion and the Lyman- photon from positronium. The maximum fractional contributions of these to the total Ps formation cross sections increase from approximately in He to in Ar and in Xe. In the case of He, good agreement is found with a coupled-state calculation; for Ar and Xe, measurements are compared with a distorted-wave Born approximation.
