1 Decay Scheme - disintegrates 19.58 (11) % by beta plus emission and 8.2 (11) % by electron capture to Fe-. - emits gamma rays with energies up to 612 and the energies and emission probabilities for many of these transitions are useful for the calibration of Ge detectors. Le cobalt se désintègre à 19,58 (11) % par émission bêta plus et à 8,2 (11) % par capture électronique vers des niveaux excités du fer. Le cobalt émets des rayonnements gamma d énergie allant jusqu à 612, ce qui le rend utile pour l étalonnage des détecteurs germanium. 2 Nuclear Data T 1/2 ( ) : 77,26 (26) d Q ( ) : 6 (2) 2.1 Electron Capture Transitions Probability Nature lg ft P K P L P M 1 ɛ,15 17,7 (2),29 (7) Allowed 6,91,8766 (17),155 (1),171 (6) ɛ,1 118, (2),167 (5) 8,1,8779 (17),1 (1),169 (6) ɛ,1 171,2 (2),2159 (18) Allowed 7,2,8816 (17),11 (1),16 (6) ɛ,12 268 (2),688 (1) Allowed 6,9,885 (16),989 (1),159 (5) ɛ,11 6,1 (2) 9,9 (18) Allowed 6,51,886 (16),972 (1),1 (5) ɛ,1 65,7 (2) 12,66 () Allowed 6,,8866 (16),971 (1),1 (5) ɛ,9 517,2 (2),965 (15) Allowed 7,,8868 (16),969 (1),155 (5) ɛ,8 79,5 (2) 16,86 (5) Allowed 6,69,8875 (16),96 (1),15 (5) ɛ,7 112,7 (2) 21, (5) Allowed 6,98,8882 (16),957 (1),15 (5) ɛ,6 1195,9 (2),15 (5) 2nd Forbidden 1,2,888 (16),957 (1),15 (5) ɛ,5 1,1 (2) 8,99 (6) Allowed 7,58,888 (16),955 (1),15 (5) ɛ, 166,1 (2),2 (6) 2nd Forbidden 1,26,8885 (16),955 (1),15 (5) ɛ,2 28,9 (2) 2, () Allowed 8,62,8888 (16),952 (1),152 (5) ɛ,1 719,2 (2),5 () 2nd Forbidden 11,6,889 (16),951 (1),152 (5) LBNL, NPL /C.M.
