Spontaneous recombination volumes of Frenkel defects in neutron-irradiated non-fcc metals

Production and production-rate curves for the non-fcc metals Fe, Mo, Ta, W, Zr, and Sn are obtained by electrical-resistivity measurements taken at 4.6 K during reactor neutron irradiations. The saturation concentration of Frenkel defects, $c_s$, and the recombination volume $v_{\mathrm{o}}$ are evaluated. A parabolic relation between the spontaneous recombination volume $v_0$ and the compressibility $\kappa$ for a series of bcc metals is found.
