TITLE=/THRESHOLD EFFECTS IN PROTON-INDUCED REACTIONS ON COPPER/;
PURPOSE=/THE BEHAVIOR OF NUCLEAR REACTION CROSS SECTIONS NEAR
THRESHOLDS IS AN ESPECIALLY SENSITIVE TEST OF ABILITY OF THE
HAUSER-FESHBACH STATISTICAL MODEL TO PREDICT THE ENERGY
DEPENDENCE OF REACTION CROSS SECTIONS. THERE SHOLD BE A DROP
IN CROSS SECTION (WIGNER CUSP) FOR ALREADY OPEN CHANNELS WHEN
A NEW CHANNEL OPENS. THESE CUSPS MIGHT BE MOST READILY
OBSERVED IN THE VICINITY OF S-WAVE NEUTRON THRESHOLDS./;
