247BK c  1979Ah03: {+247}Cf produced by irradiating {+246}Cm with 40-MeV
247BK2c  |a-particle at the Argonne cyclotron. Chemical separation of the
247BK3c  product was followed by isotope separation. |g spectra were measured
247BK4c  with a Ge(Li) detector. Cd, Cu and Al absorbers were used to reduce
247BK5c  summing-effect interference from intense Bk K x-rays.
247BK6c  The electron spectra was measured with a cooled Si(Li)
247BK7c  spectrometer with FWHM at 100 keV=1.0 keV

247BK cG M$From conversion electron data of 1979Ah03. Absolute
247BK2cG conversion coefficients were determined by measuring |g and ce spectra
247BK3cG of a {+203}Hg source at identical geometries. Multipolarities in square
247BK4cG brackets are from level scheme; they were not determined
247BK5cG experimentally.

247BK cG $The total observed K x-ray intensity is 7230 {I300}; the
247BK2cG calculated intensity due to internal conversions (153 {I10}) and those
247BK3cG due to electron captures (6250 {I996}) deduced from |e branchings and
247BK4cG theoretical K/|e ratios for Q+=613 {I16} keV yield 6403 {I996} for
247BK5cG total K x-ray intensity. Experimental K-shell fluorescence yield of
247BK6cG 0.971 {I4} (1979Ah01) was used in calculations. For Q+=570 keV,
247BK7cG the calculated total K x-ray intensity is 6682 {I1031}.
