Abstract: | The positron hydrogen charge-exchange problem has been investigated using the three-particle scattering formulation. 1s and 2s intermediate states of hydrogen atom have been taken into account for calculation of second order matrix elements. The effect of 2s term is to decrease total cross-section as compared to the results involving 1s state only. The total cross-sections results are compared with results of other calculations in the energy region 1.5 to 10 Ry. |
