A high energy-resolution 11B(3He,t)11C experiment was performed at 0° and an intermediate incident energy of 140 MeV/nucleon for the study of precise Gamow-Teller (GT) transition strengths. Two doublet states at ≈4.5 and ≈8.4 MeV were clearly resolved with a resolution of 45 keV. The strengths are compared with a calculation using an ab initio no-core shell model, which became available for the A = 11 system recently. It was found that a calculation including a three-nucleon interaction better reproduces the observed GT transition strengths.
