Abstract

This paper extends applications of the multilayered solid target H/T+D2, which is kept at 3 K. The time evolutions of muonic tritium atoms (mt) are obtained, by taking into account mt production rate at different places of deuterium material. The apparatus H/T+D2 can be used for checking nuclear properties of implanted ions, which take part at muon transfer. Electromagnetic X-rays are generated by muon atomic transitions. The muonic X-ray transition energies are strongly affected by the size of nuclei. Here, a solid hydrogen–tritium (H/T) with a 1 mm thick is used for mt production. For ion implantation, the required amount of deuterium material is determined to be about 3.2 micrometers. Moreover, the muonic X-ray yields are estimated and compared with those of the arrangement H/T+D2. While the present target requires argon ion beam intensity nearly a factor of 2 times smaller; gives a relatively higher X-ray yield (15% enhancement per hour) at the energy 644 keV with the detection efficiency of 1%.
