I have a question on the energy of the muons that decay in a plastic scintillator.
In these notes, at page 4, fourth line from the end, it is mentioned that
muons with less than about 50 MeV will stop in the scintillator (about 0.3%.)
It seems that the 0.3% mention is taken from the Bruno Rossi book, High Energy Particles (Prentice Hall, 1952). Unfortunately my local library can't provide me the book.
I would be very grateful = if someone who owns the book could check up if the 0.3 % mention is explained somewhere and share the information with me.
