MEASUREMENT OF STORED ENERGY IN QUENCHED CONDENSED COPPER AT LOW TEMPERATURES (in German)
S>Copper films are produced by quenching condensation on a substrate at low temperature. A stored energy release of 216 cal/mole and a resistivity decrease of 1.8 mu ohm-cm are observed during annealing from 20 to 60 deg K. In this temperature range the recovery of the films is described by a crystallization of highly disordered material between small crystallites, which are produced during condensation. About 14 at.% of the whole film substance take part in this process. The stored energy-resistivity ratio E/ DELTA /sub p/ found is 1.9 cal/g/ mu ohm-cm in the whole temperature range from 20 to 60 deg K. This value is in good agreement with the stored energy measurements on neutronbombarded copper. (auth)
