246CM c  2007Ko01: {+250}Cf was mass separated and prepared as a thin source
246CM2c  by electromagnetic isotope separator at Argonne National Laboratory
246CM3c  in the early 1970s. Via the ingrowth activity method, in 2006
246CM4c  |a spectra from the decay of the source was measured using passivated
246CM5c  implanted planar silicon (PIPS) detector (FWHM= 10keV) at small solid
246CM6c  angles. Deduced T{-1/2} and |a emission probabilities
246CM c  1972Sc01: Alpha decay of {+250}Cf radioactive source was studied using
246CM2c  two low-energy photon Ge(Li) detectors. Measured E|g.

246CM2cG in comments. I(ce) were normalized for subshell L3=349 by 1971Ch15.
246CM3cG The evaluator deduced the re-normalization value using
