TITLE=/VARIOUS INTERMEDIATE CHANNELS IN THE
12C+12C->12C(G.S.)+ALPHA+8BE(G.S.) REACTION/;
PURPOSE=/THE 12C+12C->12C(G.S.)+ALPHA+8BE(G.S.) REACTION HAS BEEN
INVESTIGATED BY 12C-ALPHA COINCIDENCE MEASUREMENTS AT
INCIDENT ENERGIES OF 90, 110 AND 140 MEV. CROSS SECTIONS OF
THREE KINDS OF INTERMEDIATE CHANNELS (12C+12C*, 160*+8BE AND
ALPHA+20NE*) AND OF NON-RESONANT -PARTS LEADING TO THE SAME
12C(G.S.)+ALPHA+8BE(G.S.) FINAL CHANNEL HAVE BEEN DEDUCED.
COINCIDENCE CROSS SECTIONS WERE REPRODUCED BY DWBA
CALCULATIONS/;
