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-11, Li-9) reaction at an incident energy of 800 MeV/nucleon is calculated within the Glauber theory and compared with the longitudinal one. The both distributions are not very much different at high energy. A simple hybrid model wave function[1] comprising both aspects of shell model and di-neutron cluster model gives a reasonable fit to the measured distribution.
