We have calculated the differential cross sections for the excitation 1s²S^e ® 2s²S^e transition in the hydrogen atomic system by electron impact using the basis functions (1s-2s-2p) within the R-matrix method at an incident energy 1 Rydberg. Our investigation demonstrates the structure in the differential cross sections curve.
