Measurement of muon transfer rate λpt and molecular formation rate λppµ, in solid hydrogen targets, in solid hydrogen targets

Abstract: The knowledge of muon transfer from protium to tritium is essentially theoretical and the different theoretical values disagree partially. Using solid hydrogen-tritium targets, with different tritium concentrations, we obtained precise experimental results for the transfer rate to tritium and the ppµ molecular formation rate. The time spectra of neutrons and alpha particles produced after dtµ fusion are used to determine the transfer rate lambda_pt and the molecule formation rate lambda_ppµ.
