Quasifree neutron-knockout (p,pn) reactions by a proton target from neutronrich nuclei, "Li (6He), were used to study the structure of l"Li (5He) and the momentum distribution of halo neutrons. Quasifree proton-knockout (p,2p) reactions from 11Li (6He) projectiles to loHe (5H) resonances were also

β¦ Synopsis
In an experimental study of 6He+p and 3H+p collisions at ~70 A MeV, the elastic scattering angular distributions were measured and the known excited state 6He~. 8 was observed. Comparative analysis of existing experimental data on proton elastic scattering by 4He, 6He, 6Li, 8He, 9Li, and ~ Li was performed. Effects of valence neutrons were investigated using the eikonal approach. A difference between ULi and 6'SHe was found. (~) 1997 Elsevier Science B.V.

While 11 Li is known to be a halo nucleus with two neutrons around a 9 Li core, the neutrons in 6 He are predicted to form a skin around its 4 He core. Both nuclei have very low breakup thresholds. To understand the structure and reaction dynamics of these nuclei, a consistent analysis of the availa
