 TITLE=/VOLUME INTEGRALS FOR LOW-ENERGY P+208PB OPTICAL POTENTIALS/;
 PURPOSE=/PROTON ELASTIC SCATTERING ON 208PB HAS BEEN THE OBJECT OF
          NUMEROUS THEORETICAL AND EXPERIMENTAL INVESTIGATIONS, SINCE
          THIS HEAVY NUCLEUS IS VERY SIMILAR TO NUCLEAR  MATTER AND
          SINCE MANY OF THE DIFFICULTIES ENCOUNTERED IN OPTICAL-MODEL
          ANALYSIS OF PROTON-NUCLEUS SCATTERING ARE NOT PRESENT. VAN
          OERS ET AL. HAVE PRESENTED A MULTI-ENERGY ANALYSIS FROM
          15-1000MEV, WHERE THEY FOUND A LINEAR ENERGY DEPENDENCE FOR
          THE REAL VOLUME INTEGRAL PER NUCLEON.  IT IS THE AIM OF THE
          PRESENT INVESTIGATION TO EXTEND THE ENERGY RANGE FAIRLY BELOW
          THE COULOMB BARRIER AND TO STUDY THE ENERGY DEPENDENCE OF THE
          REAL AND IMAGINARY VOLUME INTEGRALS./;
