We find significant direct e/sup +/ production in hadron collisions at 10, 15, and 24 GeV/c and direct e/sup -/ production at 24 GeV/c, at theta/sub c.//sub m./ =90degree at 0.5< or =P/sub T/< or =1.5 GeV/c. The e/..pi.. ratio rises at low P/sub T/, and in all cases exceeds the level predicted from known sources for P/sub T/ approximately-less-than1 GeV/c. (AIP)
