Abstract
Transverse and longitudinal momentum distributions of Li-9 fragments f rom Li-11 break-up reactions in C, Al and Pb targets have been measure d at 280 MeV/u. The two-neutron removal cross-section was measured to be sigma(-2n), = 0.26 +/- 0.02 b for the carbon target, sigma(-2n) = 0 .47 +/- 0.08 b for the aluminum target and sigma(-2n), = 1.9 +/- 0.4 b for the lead target. No significant difference is observed between th e narrow widths (FWHM approximate to 47 MeV/c) of the transverse and l ongitudinal momentum distributions of the Li-9 fragments. The physical implications of this are discussed.
