摘要：
A model independent theoretical analysis of neutron polarization observables in d((gamma)over-right-arrow, (n)over-right-arrow)p using circularly polarized photons at the range of energies of interest to Big Bang Nucleosynthesis is presented. An investigation of various spin dependent observables is carried out including the isoscalar multipole amplitudes M1(s). and E2(s). It is suggested that the measurement of neutron polarization in the final state at near threshold energies will be very useful to assess the contribution of isoscalar amplitudes at range of energies of interest to Big Bang Nucleosynthesis.
