Positron-impact excitation of helium

Journal Article · · Phys. Rev. A; (United States)
The positron-impact excitation cross section for the n = 2 level of helium has been calculated in the energy range 20--200 eV. A distorted wave obtained by solving an adiabatic equation has been used in the initial channel. The results are compared with the other existing theoretical predictions and measured values.
