 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/;
