TITLE=/EXCITATION FUNCTION OF GIANT RESONANCES AS DOORWAY STATES IN THE
12C(P,P)12C REACTION BETWEEN 19 AND 23 MEV/;
PURPOSE=/THE AIM OF THIS WORK IS TO USE A COMPLEMENTARY WAY OF
DETERMINING THE PROPERTIES OF THEGIANT RESONANCES, THROUGH THE
STUDY OF INELASTIC SCATTERING TO LOW-LYING STATES. THIS OCCURS
WHEN THE PROJECTILE ENERGY IS SUCH THAT MULTI-STEP SECOND
ORDER SCATTERING PROCESSES MEDIATED BY VIRTUAL FORMATION OF
THESE GIANT RESONANCES ARE COMPARABLE TO THOSE OF THE NORMAL
DIRECT REACTION. THE INTERST OF THE INCIDENT ENERGY REGION
LIES IN THE FACT THAT THE EXCITATION ENERGY OF THE VIRTUAL
CORE EXCITED STATES CORRESPONDS TO THE LOCATION OF GIANT
DIPOLE AND QUADRUPOLE RESONANCES./;
