245BK c 1989Ha27: {+249}Es was produced by {+249}Cf(p,n), Ep= 23 MeV. The |a
245BK2c decay was studied with 12 Si(Au) surface barrier detector.
245BK3c The |a-energy resolution (FWHM) of the sum of |a-spectra observed
245BK4c by twelve detectors was about 35 keV for the 8.784 MeV |a-group of
245BK5c {+212}Po. Determined E|a, I|a.
245BK c 1970Ah01: {+249}Es was produced by {+249}Bk(|a,4n). The |a
245BK2c decay was studied with a Si(Au) surface barrier detector.
245BK3c Determined E|a, I|a.
245BK c
245BK cA E,IA$From 1989Ha27.
245BK cA HF$The nuclear radius parameter r{-0}({+245}Bk)=1.4820 {I36}
245BK2cA is deduced from interpolation (or unweighted average) of radius
245BK3cA parameters of the adjacent even-even nuclides.
