“…Therefore, our knowledge on the types of defects in hexagonal metals is less developed than in cubic metals. In Co mainly electrical resistivity measurements have been used to study the recovery spectra after electron [2] and thermal neutron [3] irradiation. The dependence of the low-temperature recovery spectra on the electron energy and the direction of the electron beam with respect to the crystallographic axes has been investigated by Maury et al [4,5].…”

After electron irradiation at 4.2 K with different doses the annealing behaviour of the electrical resistivity of Co is studied between 15 and 550 K. Two stages at 65 and 300 K show a dose-dependent temperature shift which may be attributed to the free migration of defects. As the annealing spectrum is found to be rather complex the influence of impurity atoms on the annealing of the radiation-induced defects cannot be excluded. Nach Elektronenbestrahlung bei 4,2 K wird die Erholung des elektrischen Restwiderstandes imTemperaturbereich zwischen 15 und 550 K untersucht. Zwei Stufen bei 05 und 300 K zeigen eine dosisabhiingige Temperaturverschiebung, was auf eine freie Wanderung von Defekten hinweist. Das Erholungsspektrum ist insgesamt recht kompliziert und der EinfluB von Verunreinigungen auf das Ausheilen der durch Bestrahlung erzeugten Fehlstellen kann nicht ausgeschlossen werden.

The recovery of rhenium after neutron irradiation a t w 390 OK has been studied u p t o 1130 O K by means of electrical resistivity measurements a t 4.2 OK. Two irradiations were performed in the BR2 reactor a t Mol: one u p t o a fluence of 7.6 x 1018 n cm-2 (thermal) and 4.3 x lo1' n (fast, E > 1 MeV) and the other one up to a fluence of 3.2 x 1019 n cmV2 (thermal) and 1.8 x lo1* n cm-2 (fast, E > 1 MeV). The irradiation induced resistivity is only partially recovered a t 1130 OK, where the annealing of defects is supposed t o be complete. This effect is attributed to the transmutation of rhenium into osmium and tungsten. The annealing spectrum between 400 and 1130 OK consists of several peaks, the main peak occurring a t about 650 OK (0.19 Tm) preceded by a subpeak a t about 620 OK. The latter one is more clearly resolved for the lower irradiation dose. This is also the case for the minor peaks occurring a t about 490 and 540 OK. Towards higher temperature continuous recovery occurs in the temperature interval 800 t o 1000 OK, whereas a small annealing

“…On the other hand, the effective threshold Ed as determined with the full theory (eq. (4) 19) after thermal neutron irradiation are suggestive of the recombination of a variety of close Frenkel pairs each with different interstitial-vacancy separation. Regarding the location of TFIA, DiCarlo, Snead, and Goland (ref.…”
