We have studied the helium plasma in the hypernetted-chain approximation considering both short-ranged internuclear and long-ranged Coulomb interactions. The optimal two-particle wave function has been determined in HNC/0 and HNC/4 approximations. The two-particle distribution functions, which have been calculated in various orders of HNC/n approximations (n = 0, 4, 5), are used to determine the pycnonuclear triple-alpha-fusion rate in the density regime 108 <= ϱ <= 1010 g/cm3. The effect of this rate on the crust evolution of an accreting old neutron star is discussed. Our calculation supports the idea that the helium liquid undergoes a phase transition to stable 8Be matter at densities ϱ ~ 3 × 109 g/cm3 as the plasma induced screening potential then becomes strong eno ugh to bind the 8Be ground state.
