Experimental study of nuclear fusion reactions in a ptμ system

By means of muon catalysis we study the phenomena in a pt-fusion, which have been previously investigated in the only experiment and now are at the frontier of nuclear few-body physics. The experiment is aimed at measuring the yields of the reaction products: γ-quanta, conversion muons and e + e − pairs. As a result we plan to measure the pt-fusion partial product yields (first time for e + e − pairs) with accuracy not worse than 10%, and this will enable us to obtain the nuclear reaction rates in M1 and E0 transitions in A = 4 system.
