Abstract The rates of the breakup reactions λB(3He) and λB(4He) in nuclear muon capture by3He and4He have been measured. The measurements were performed on the muon beam of PSI with a multi-anode high-pressure ionization chamber filled with isotopically pure3He or4He at 120 bar. The chamber was used as a target and detector for both the incoming muons and for the charged reaction products (tritons, deuterons and protons) of the breakup reactions ΛB(3He) and ΛB(4He). Our statistics, about 5 × 105 of breakup events, provides a possibility to improve the precision of evaluated rates. The preliminary results: λB(3He)=720 ± 70 s−1, λB(4He)=415 ± 40 s−1 are compared to theoretical predictions and to previous experiments.
