  A low-energy enhancement of the gamma-ray strength function in several light
and medium-mass nuclei has been observed recently in 3He-induced reactions. The
effect of this enhancement on (n,gamma) cross-sections is investigated for
stable and unstable neutron-rich Fe, Mo and Cd isotopes. Our results indicate
that the radiative neutron capture cross sections may increase considerably due
to the low-energy enhancement when approaching the neutron drip line. This
could have non-negligible consequences on r-process nucleosynthesis
calculations.
