The results of calculations of nucleosynthesis of heavy elements during the explosion of a low-mass neutron star are presented. The low-mass neutron star is formed as a result of the exchange of matter in the last stages of the evolution of a close binary system of neutron stars with a large initial mass asymmetry. Two variants of the scenario, which use different approximations of the equation of state of neutron star matter: BSk22 and BSk25, are considered. Their usage lead to different expansion dynamics of the shells of a low-mass neutron star. It is shown that the character of shock wave propagation and the abundance of heavy elements formed in the inner layers of the outer crust with 0.29 < Ye < 0.45, for these two scenarios are different, although the composition of the outer crust before the explosion differs insignificantly. These differences in the scenarios result in a noticeable difference in the calculated abundances of heavy elements both in these layers and in the entire examined part of the outer crust.
