 TITLE=/ Subthreshold antiproton production in pA, dA and alpha A
         reactions /;
 PURPOSE=/ To examine the antiproton production cross section in the
           case of light ions, since a large cross section had been
           observed in heavy-ion reactions; however unexpectedly, large
           cross sections were also found in the light-ion-induced
           reactions relative to proton-induced reactions. /;
