247BK c 1979Ah03: {+251}Es produced from decay of {+251}Fm followed by mass
247BK2c separation. The |a-particle spectrum was measured with the Argonne
247BK3c double focussing magnetic spectrometer (FWHM=5 keV) and Au-Si
247BK4c surface barrier detector (FWHM|?13.0 keV)
247BK cA E$From 1979Ah03. Uncertainties are from spectrometer calibration.
247BK cA IA$Alpha intensities per 100 |a decays, measured by 1979Ah03
247BK CA HF$r{-0}({+247}Bk)=1.4753 83, unweighted average of
247BK2CA r{-0}({+246}Cm)=1.4836 5 and r{-0}({+248}Cf)=1.4670 8 (1998Ak04),
247BK3CA is used in calculations of HF.
