  Large-scale QRPA calculations of the E1-strength are performed as a first
attempt to microscopically derive the radiative neutron capture cross sections
for the whole nuclear chart. A folding procedure is applied to the QRPA
strength distribution to take the damping of the collective motion into
account. It is shown that the resulting E1-strength function based on the SLy4
Skyrme force is in close agreement with photoabsorption data as well as the
available experimental E1-strength at low energies. The increase of the
E1-strength at low energies for neutron-rich nuclei is qualitatively analyzed
and shown to affect the corresponding radiative neutron capture cross section
significantly. A complete set of E1-strength function is made available for
practical applications in a table format for all 7<Z<111 nuclei lying between
the proton and the neutron drip lines.
