Abstract

To extract the neutrino mass from a beta-spectrum the accurate knowledge of the resolution function (RF) is of crucial importance. Usually some known internal conversion lines are used to determine the instrumental RF. For this purpose one has to know the natural width of the internal conversion lines.
