TITLE=/PRODUCTION OF ARGON ISOTOPES BY SPALLATION OF SC, TI, FE, CO,
NI, AND CU/;
PURPOSE=/ALTHOUGH THE GENERAL CHARACTERISTICS OF SPALLATION REACTIONS
ARE NOW WELL KNOWN, CERTAIN ASPECTS ARE NOT YET ENTIRELY
CLEAR. TWO OF THESE ARE THE SUBJECT OF THE PRESENT STUDY.
(A)HOW IMPORTANT IS THE INFLUENCE OF TARGET COMPOSITION ON THE
FINAL DISTRIBUTION OF SPALLATION PRODUCTS, IN THE CASE OF
MEDIUM-MASS TARGETS ? (B)THE EXCITATION FUNCTIONS FOR THE
SPALLATION REACTIONS INCREASE RAPIDLY BETWEEN THE REACTION
THRESHOLD AND ABOUT 1 GEV, THEN TEND TOWARDS AN ASYMPTOTIC
VALUE, WITH NO SIGNIFICANT VARIATION BEING OBSERVED ABOVE
ABOUT 10 GEV. IT IS YET TO BE DETERMINED, HOWEVER, WHETHER
THE CROSS SECTIONS GO THROUGH A MAXIMUM SOMEWHERE IN THE 1 TO
10 GEV INTERVAL./;
