        THE (N,N')ALPHA-D CROSS SECTION WAS BASED ON THE MEASURE- 
        MENT OF ROSEN AND STEWART /15/.  THE CONTRIBUTION FROM    
        MT=53, 59 AND 63 WAS SUBTRACTED SO THAT SIG-T MIGHT BE    
        EQUAL TO THE SUM OF PARTIAL CROSS SECTIONS. THE CROSS     
        SECTION FOR EACH LEVEL WAS CALCULATED BY THE 3-BODY PHASE-
        SPACE DISTRIBUTION WITH A CORRECTION OF THE COULOMB       
        INTERACTION IN THE FINAL STATE, ASSUMING ISOTROPIC CENTER-
