The reactions 4He(e, e' p3He)pi- and 4He(e, e' p3He)pi0 were studied simultaneously, and for the first time, in a large kinematical domain including the Delta-resonance region. This was achieved by detecting the recoiling 3He and 3H nuclei instead of the emitted pions. The dependences of the cross section on the recoil momentum p(rec), the invariant mass WpiN, and the direction thetapi,q' and phipi,q' of the produced pion, are globally well described by the results of (quasifree) distorted-wave impulse approximation calculations. However, in the Delta-resonance region there are clear discrepancies, which point to medium modifications of the Delta in 4He.
