Determination of the astrophysical 8Li(n, )9Li reaction rate from the measurement of 2H(8Li,9 Li)1H reaction

The cross section of the 8Li(n, )9Li reaction has attracted much attention for many years because of its importance in nuclear astrophysics. The single particle spectroscopic factor, S1,3/2 for the ground state of 9Li = 8Li n derived from the transfer reaction of 8Li(d, p)9Li was used to calculate the direct radiative capture reaction rates of 8Li(n, )9Li at energies of astrophysical interest. The present result shows that the 8Li(n, )9Li direct capture reaction may play an important role in the astrophysical environments of inhomogeneous big bang and type II supernovae.
