| Abstract: Photodisintegration of lithium is important in the field of Nuclear Physics, Particle Physics and Astrophysics. 7Li is considered as one of the elements that was primordially synthesized in standard Big Bang Nucleosynthesis. Lithium, being fragile, gets destroyed easily at relatively low temperatures. WMAP measurements have inferred that 7Li abundance is two to three times higher than that inferred by the low metallicity halo stars [2]. In stars, lithium exists with two isotopes 6Li as well as 7Li. Series of experimental measurements on the photodisintegration of lithium isotopes are being carried out at High Intensity Gamma Ray Source to study the cross section and angular dependence [3]. In addition, experimentalists are launching the Extreme Light Infrastructure Silicon Strip Array (ELISSA) through a collaborative effort between LNS-INFN and ELI-NP, offering the widest possible angular coverage for studying nuclear reactions relevant to astrophysics. This facility will help improve our understanding of stellar evolution [4]. However, the theoretical studies are still fewer compared to the experimental investigations. Therefore, the purpose of the present contribution is to study neutron polarization in the 7Li + γ → 6Li + n reaction using model model-independent approach. In this study, we have included the role of E1, M1 and E2 multipole amplitudes in 7Li + γ → 6Li + n reaction.
