We study the phase diagram of the flux lines using the mapping to
two-dimensional bosons interacting via the Yukawa potential in the
hypernetted-chain approximation. The pair-correlation function,
static structure factor, and spectrum of the excited energies are
calculated over a wide range of the parameter. These quantities
are used for studying the freezing transition from the entangled
vortex liquid into the Abrikosov lattice. The resulting B-T phase
diagram is in good agreement with the known estimates for the
vortex lattice phase diagram and the Monte Carlo simulations.
