Low-temperature electron-irradiation effects in Zn

Abstract
The atomic displacement and recovery mechanisms of Low-temperature electron-irradiated Zn have been studied. Detailed annealing data are presented showing several distinct recovery stages below 70 K. One first order stage at 9.5 K is shown to have an activation energy of 0.015 ± 0.003 eV while there is evidence of slight dose dependence in the range 11–16 K. Several minor stages are resolved above 16 K for high dose irradiation. Threshold displacement data generally confirm earlier investigations. Previous results on several low-temperature irradiated h.c.p metals are reviewed and a number of common features are found.
