Previous studies of elastic pi /dup -/ scattering on C at less than 22 Mev indicated the presence of an effective repulsion potential. An analysis of pi /sup -/ scattering at identical energies was made in order to determine the pi /sup -/nucleus potential by the difference in the interference of electromagnetic and nuclear interactions. A 370 x 140 x 100 mm propane bubble chamber irradiated by a 5 to 15 Mev pi /sup -/ beam was used in the experiment. The tabulated results, compared with the data for 4pi/sup +/, revealed a region (20 to 120 deg angle) where the pi /sup -/ scattering is much weaker than the pi /sup +/. Further studies showed that in the weaker region the contributons of interfering Coulomb and nuclear interactions are highly pronounced. The divergence in the angular distributions of pi /sup -/ and pi /sup +/ permit a direct determination of the pi -carbon nucleus potential that corresponds to BETA -state repulsion. The obtained data were used for evaluating the phase shifts in pi /sup -/ scattering on C and, in turn, the BETA -state repulsion. The data are in close agreement with those of N. Byers (Phys. Rev 107: 843(1957)). (R.V.J.)
