The experimental values of a, the fractional increase in resonance capture per °C, have a spread many times the quoted errors. The use of different slowing-down spectra has contributed to the discrepancies. For uranium metal, approximate corrections are made to obtain the coefficient <em>α</em><sub>0</sub> appropriate to a <span><math><mtext>1</mtext><mtext>E</mtext></math></span> spectrum. The spread in the corrected values <em>α</em><sub>0</sub> is smaller than that for α, but remains unsatisfactory. Other experimental difficulties arise in reactivity normalizations, in obtaining the statistical weight of samples and from spurious temperature effects. Theory and experiment agree on an increase of <em>α</em><sub>0</sub> with increasing surface-to-mass ratio and that this is caused by an increase in the contribution of lower-energy resonances to the Doppler effect. It is also in agreement with the theoretical interpretation of the radial dependence of the Doppler effect in a lump. However in the region of practical interest where the surface-to-mass ratio is small, <em>α</em><sub>0</sub> is almost constant. Experimental evidence on the temperature behaviour of <em>α</em><sub>0</sub> is unsatisfactory but indicates that <em>α</em><sub>0</sub>, decreases with increasing temperature.

Unlike PTFE and polytrifluorochlorethylene, rubberlike Kel-F type fluorinated copolymers become cross-linked when irradiated.
