Abstract

The reactions He4(e,eâ€pHe3)Ï€- and He4(e,eâ€pHe3)Ï€0 were studied simultaneously, and for the first time, in a large kinematical domain including the Î"-resonance region. This was achieved by detecting the recoiling He3 and H3 nuclei instead of the emitted pions. The dependences of the cross section on the recoil momentum prec, the invariant mass WÏ€N, and the direction ÎÏ€,qâ€ and Ï•Ï€,qâ€ of the produced pion, are globally well described by the results of (quasifree) distorted-wave impulse approximation calculations. However, in the Î"-resonance region there are clear discrepancies, which point to medium modifications of the Î" in He4. © 2005 The American Physical Society.
