delta. /sup + +/ resonance in a /sup 11/B nucleus

We have measured the cross section of the reaction /sup 12/C(..pi../sup +/,..pi../sup +/p) 11 in the region of the ..delta../sup + +/ resonance to determine whether the width or central energy of the resonance are modified if ..pi..,p scattering takes place inside a nucleus. No significant changes were found within the accuracy of our experiment.
