Abstract:

In this paper, we focus our attention and deal with positron impact excitation of n=2 state of Helium from its ground state with the point of view of angular correlation parameter (g) at 50eV. To calculate this parameter, distorted wave approximation theory with different choices of distorted potential has been used. The result for 1¹S-2¹S transition is compared with available theoretical and experimental data. We found that these obtained results are quite sensitive to choice of distortion potential used.
