The differential elastic scattering cross sections for protons from 12C nuclei have been measured for incident proton energies from 150 to 1203 keV, believed to be accurate to 10%, using a recently constructed precision scattering chamber. Excitation functions have been measured at the centre-of-mass angles 90° and 170° and angular distributions from 10° to 170° have been measured at 231, 344, 402, 443, 457, 470, 747, 975 and 1203 keV. The 1/2+ state in 13N was observed near 457 keV in p-12C scattering. A set of parameters has been derived for a global optical potential from elastic p-12C scattering with present range of energy. The optical model predictions were tested with data from present experiment. |
