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./;
