Abstract
The experiment presented measures the relative differential cross sections in helium for the energies between 1.0 and 10.0 eV and at the angles 10°, 15°, 20°, 25°, and 30°. The results are compared to the experiments of others and are also compared to the present theories. Since experiments do not overlap very well in this region, conclusions are difficult to draw. It is easier, however, to make comparisons to the theoretical predictions. It is shown that the results of this experiment do not agree well with the theoretical predictions.Keywords
