Atomic capture of Μ−-mesons in chemical compounds

Molecular Structure Effects on Atomic and Nuclear Capture of Mesons

“…(d) Sharp deviations fr om the Z-Iaw (9,26) are quite natural with the above assumption. In particular, the periodic dependence of the quantity A(Z/O) in oxides Zk Om (Figure 4) is a natural consequence of the periodic change of the number of external electrons v with monotonically increasing number Z. Th en periodic changes of the Kv-series intensity should also be expected, and the curves of Figure 5 appear to be a fr agment of the curve of the type presented in Figure 4.…”

“…The results of the verification of the Z-law validity are given by Baijal et al (9) in Figure 1. The straight lines correspond to the formula kW(Z)/mW(Z') = (Z/Z')"…”

Antiproton annihilation physics in the Monte Carlo particle transport code SHIELD-HIT12A

“…Baijal et al [20] measured a substantial number of capture probability ratios WðZÞ=WðZ 0 Þ for l À projectiles. Their results corresponded to rðZÞ / Z k , with values of k varying from À1 to +1.5.…”

“…(20) gives the total dose stemming from all antiprotons in one spill, but in order to compare the measured dose with the simulated dose, the number of antiprotons exiting the beam nozzle then has to be known.…”

Muon Transfer Rates from Muonic Hydrogen Atoms to Gaseous Benzene and Cyclohexane

“…The muon capture probability strongly depends on the molecular chemical structure of the muon-capturing atom. [5][6][7] For example, muon capture ratios per atom of carbon compared to those of oxygen are different between CO 2 molecule and CO molecule. 8 Similar studies have also been intensively carried out with a negative pion; and because the negative pion has a similar mass to that of the negative muon, the formation processes for pionic atoms and muonic atoms are thought to be very similar.…”
