Research Abstract |
In this study, muon irradiations for low-pressure gaseous samples (CO, CO2 and COS) have been performed at the muon science facility (MUSE) in J-PARC. The muon capture probabilities for C and O atoms and the initial quantum level (principle and angular momentum quantum numbers) of captured muons were quantitatively investigated for these molecules. From this work, we found that the muon capture probability for C atom in CO molecule was clearly higher than that in CO2 and COS molecules. We also found that the initial quantum level of muon captured in C atom for CO molecule was different from that for CO2 and COS molecules. We concluded that the difference in muon capture process in C atom among these molecules are caused by lone-pair electrons at C atom in CO molecule, and we firstly investigated the initial quantum levels of captured muon by lone-pair electrons at C atom quantitatively.
