| Outline of Final Research Achievements |
In this study, muon transfer processes for CO, CO2, C6H6 and C6H12 molecules were studied at the muon science facility (MUSE) in J-PARC. The muon transfer rates for carbon atom of these molecules were determined from muonic X-ray intensities of muonic carbon atom. There are no differences on muon transfer rates among these molecules in low pressure gaseous condition. On the other hand, we found muon transfer rate for carbon atom in C6H6 molecule is 1.5 times higher than that in C6H12 molecule in high density liquid sample condition. From these results, we conclude that molecular effect on muon transfer process was firstly observed in the prompt muon transfer phenomena that derived from excited muonic hydrogen atoms.
