Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

I ran rdecay01 with attached macro : Eu152.txt The secondary spectrum are plotted by species : gamma.jpg neutrino.jpg electron.jpg On gamma.jpg you see peak at 780 keV is of the same order of the 960 keV There is also a neutrino peak around 780 keV. Could be contribute to the overestimation ?
