TRANSVERSE-MOMENTUM DISTRIBUTIONS OF A LI-9 FRAGMENT IN THE (LI-11, LI-9) REACTION AND NEUTRON CORRELATIONS

The transverse momentum distribution of a Li-9 fragment from the (Li-1 1, Li-9) reaction at an incident energy of 800 MeV/nucleon is calculat ed within the Glauber theory and compared with the longitudinal one. T he both distributions are not very much different at high energy. A si mple hybrid model wave function[1] comprising both aspects of shell mo del and di-neutron cluster model gives a reasonable fit to the measure d distribution.
