Differentielle Wirkungsquerschnitte für die elastische Streuung niederenergetischer Elektronen an Kalium

The elastic differential cross sections of electrons scattered by potassium has been measured over the angular range from 25 ° to 150 ° and with electron energies between 0.9 and 15 eV. The results are compared with other experimental data and with theoretical values. The agreement is only partly satisfactory.
