Muon capture in oxides using the lifetime method

The relative capture rate has been measured for muons stopping in 22 oxides. The experimental method was to detect the decay electrons and to use the unique lifetime signature to determine which element captures the muon.     

Isospin violation in α-induced reactions

A study has been made of the reactions ¹²C(α, α')¹²C and ¹⁰B(α, d)¹²C which lead to the 12.71 MeV T = 0 and the 15.11 MeV T = 1 levels in ¹²C. Significant structure is observed in the yield curves of the reactions ¹²C(α, α') ¹²C for both the isospin allowed and forbidden reactions up to the maximum available α-energy of 27 MeV; this structure is attributed to compound nucleus formation. No significant structure is observed in the reaction ¹⁰B(α, d)¹²C.     

Branching ratios for stopped pions in deuterium

The ratios $\text{S =}\text{ω(π}{}^{\mathrm{?}}\text{d}\text{→}\text{nn}\text{)}\text{ω(π}{}^{\mathrm{?}}\text{d}\text{→}\text{nn}\text{γ)}$ has been measured for negative pions stopping in deuterium gas at pressures up to 100 atm. The result is S = 2.83 ± 0.04 which is a factor of two more accurate than previous measurements.
