We present a precise measurement of 3He analyzing powers for p-3He elastic scattering with the polarized 3He target at 50, 65, 70, and 100 MeV. The data at 65 and 70 MeV are compared with the theoretical predictions based on the modern nucleon-nucleon potentials. Large discrepancies between the data and the predictions are clearly seen at the angles where the 3He analyzing power takes the minimum and maximum values, which are not explained by Δ-isobar effects.
