For these exotic nuclei, radiative neutron capture is extremely sensitive to their $\\gamma$-emission probability at very low $\\gamma$ energies. In this work, we present measurements of the $\\gamma$-decay strength of $^{70}$Ni over the wide range $1.3 \\leq E_{\\gamma} \\leq 8 $ MeV. A significant enhancement is found in the $\\gamma$-decay strength for transitions with $E_\\gamma < 3$ MeV.
