EXPS 632/878: relativistic density squared effects in proton-nucleus scattering at 500 and 800 MeV

Following the success of Relativistic Impulse Approximation (RIA)-Dirac equation descriptions of intermediate energy proton-nucleus scattering data, several independent theoretical research efforts have been initiated. In this section the authors discuss a recently approved proposal to obtain new data aimed specifically at testing some of the new physics in the RIA-Dirac equation approach. EXP 632/878 will provide data for the pair 54Fe-48Ca at 500 and 800 MeV. Since high quality 48Ca data were obtained in EXP 425/433, only enough 500 MeV 48Ca data will be obtained to eliminate systematic errors between the 54Fe and 48Ca angular distributions (relative absolute normalization and relative absolute angle). The experiment will also extend the 800 MeV p + 54Fe and 48Ca elastic angular distributions to about 300 because the EXP 311 data only extends to about 220, and experience has shown that such data must extend to about 300 in order to minimize in the analysis contributions from statistical and model dependence
