Muon transfer from thermalized muonic hydrogen isotopes to argon

Low-energy direct muon transfer from H to Ne10+, S16+and Ar18+using the two-state close-coupling approximation to the Faddeev-Hahn-type equation

“…[12,13]. In the case of muon transfer from (dµ) 1s to Ar 18+ , we find in Table II that the total transfer rate has decreased in this case compared to that in Table I, in agreement with the observed experimental trend [9]. For the rates reported in Table II a constant value is obtained for E ≤ 0.04 eV.…”

“…The present total transfer rate of (12.9 ± 0.4) × 10 10 s −1 is in good agreement with experiments of Refs. [9][10][11]. However, it disagrees strongly with experiments of Refs.…”

“…The present total transfer rate of (5.3 ± 0.4) × 10 10 s −1 for (dµ) 1s to argon is in reasonable agreement with the experimental rates of Refs. [9,14].…”

“…have been the subject of many experimental investigations [9][10][11][12][13][14][15][16][17], where H stands for the hydrogen isotope proton (p) or deuteron (d) and X Z+ stands for the target nuclei. Investigations of the low-energy muon-transfer reactions in collisions of muonic hydrogen H µ with nuclei X Z+ are of importance for the muon-catalyzed fusion cycle [18].…”

“…There have been several experiments for muon transfer from pµ to argon which yielded transfer rates centered around the following five different values: (16.3 ± 0.9) × 10 10 s −1 [9], (12.0 ± 1.9) × 10 10 s −1 [10], (14.6 ± 1.4) × 10 10 s −1 [11], (35 ± 6) × 10 10 s −1 [12] and (98 ± 15) × 10 10 s −1 [13]. For muon transfer from dµ to argon the experimental transfer rates are (8.6 ± 0.4) × 10 10 s −1 [9] and 9.4 ×10 10 s −1 [14]. The experimental situation in the case of argon is quite controversial with widely different values for the transfer rates, specially in the case of pµ.…”
