摘要：

The R-matrix method has been employed to study the electron excitation of atomic helium. Nineteen states (n = 1, 2, 3, 4) have been included in the expansion of the total wavefunction. The results of this 19-state calculation are used to obtain the electron-photon coincidence parameters lambda and /chi/ for the excitation of 1(1)S --> 3(3,1)P at 29.6 eV. The calculated parameters lambda and /chi/ are compared with the only available experiments.
