“…This formula includes a 1/1" dependence (r being the atomic radius) which is in agreement with the observation [-5, 9-13] that atoms with smaller radii show larger capture probabilities. This radius dependence is also related to the observed valence dependence [14] in chemical compounds. The Coulomb capture in inhomogeneous matter was recently calculated [,15, 16].…”

“…Several studies have investigated the formation process of muonic atoms, and the muon capture probability for each atom in a material has been measured. These studies indicated that the muon capture probability is affected by the chemical environment, such as the molecular structure [15][16][17][18][19][20][21][22][23]. This known as the chemical effect [22].…”

Chemical effect on muonic atom formation through muon transfer reaction in benzene and cyclohexane samples

To investigate the chemical effect on the muon capture process through a muon transfer reaction from a muonic hydrogen atom, the formation rate of muonic carbon atoms is measured for benzene and cyclohexane molecules in liquid samples. The muon transfer rate to carbon atoms of the benzene molecule is higher than that to the carbon atoms of the cyclohexane molecule. Such a deviation has never been observed among those molecules for gas samples. This may be because the transfers occur from the excited states of muonic hydrogen atoms in the liquid system, whereas in the gas system, all the transfers occur from the 1s (ground) state of muon hydrogen atoms. The muonic hydrogen atoms in the excited states have a larger radius than those in the 1s state and are therefore considered to be affected by the steric hindrance of the molecular structure. This indicates that the excited states of muonic hydrogen atoms contribute significantly to the chemical effects on the muon transfer reaction.
