Abstract

Abstract—This report presents the results of an experiment aimed at observation of the muon catalyzed ³Hed fusion reaction ³He + (3.66 MeV) + p (14.64 MeV) + μ which might occur after a negative muon stop in the D₂ + ³He gas mixture. The basic element of the experimental setup is a Time Projection Chamber (TPC) which can detect the incoming muons and the products of the fusion reaction. The TPC operated with the D₂ + ³He (5%) gas mixture at 31 K temperature. About ³Heμd molecules were produced with only 2 registered candidates for the muon catalyzed ³Hed fusion with the expected background events. This gives an upper limit for the probability of the fusion decay of the ³Heμd molecule at 90% C.L. Also presented are the measured formation rate of the ³Heμd molecule and the probability of the fast muon transfer from the excited to the ground state of the atom. The obtained results are compared with the previously published data.
