Abstract
The neutron-capture conversion-electron spectrum of the207Pb (n, e)208Pb reaction has been measured between 2 and 7.5 MeV. Only the weakK-line from the 7,368 keV transition has been observed. The upper intensity limits for conversion electron lines have been estimated to be 5 · 10−4 per capture between 4 and 5 MeV. A graph shows the ratio of internal pair formation to internalK conversion forE0-transitions.
