Target structure independent Li→7 elastic scattering at low momentum transfers

Abstract Analyzing powers and cross sections for the elastic scattering of polarized 7 Li by targets of 6 Li, 7 Li and 12 C are shown to depend only on the properties of the projectile for momentum transfers of less than 1.0 fm −1 . The result of a detailed analysis of the experimental data within the framework of the coupled channels model with ground state reorientation and transitions to the excited states of the projectile and targets included in the coupling schemes are presented. This work suggests that nuclear properties of weakly-bound nuclei can be tested by elastic scattering experiments, independent of the target used, if data are acquired for momentum transfers less than ∼ 1.0 fm −1 .
