Resume.- On a determine Ia distribution des separations en energie des niveaux de ('etat fondarnental de I'accep-teur dans descristaux Si(B) tres purs en mesurant I'absorption resonnante ultrawnore dans une gamme importante de frequences. Les distributions mesurees se comparent bien avec lesdistributions attenduesdes champs electriques des = = lOll em- 3 donneurs residuels. On a mesure I'inttnsire critique pour saturer I'attenuation resonnante dans des cristaux avec differentes concentrations d'aocepteurs et eo fonction de la temperature. Bien que Ia distance: moycnne des accepteurs soit beaucoup plus grande que Ie rayon de Bohr des trollS lies 00 trouve que Its temps de relaxation sont raccourcis par I'in...
