 TITLE=/Momentum distribution of 15B fragments from the breakup of
        17B/;
 PURPOSE=/Little is known about 17B, which has been considered to be
          candidate halo structure, beyond its matter radius, and it is
          important to mesure the longitudinal momentum distribution for
          15B fragments from the breakup of 17B in order to obtain more
          detailed structure information./;
