244BK c 1989Ha27: {+248}Es produced by {+249}Cf(p,2n) at the
244BK2c 88 inch cyclotron at Lawrence Berkeley Laboratory and the Tandem
244BK3c Van de Graaff accelerator at the Japan Atomic Research Institute
244BK4c with Ep=18-33 MeV. |a particles from the decay of the reaction
244BK5c products were measured with Si(Au) surface barrier detectors.
244BK c 1970Ah01: {+248}Es produced by {+249}Bk({+3}He,4n) reaction at the
244BK2c Argonne 152.4 cm cyclotron. The isotope was characterized using
244BK3c the recoil technique. The energy of the {+248}Es |a group was
244BK4c measured with a Au-Si surface barrier detector
244BK c 1956Ch67: {+248}Es identified via {+249}Cf(d,3n) reaction at the
244BK2c 60 inch cyclotron at Crocker Laboratory with E(d)=18-22 MeV.
244BK3c The branching ratio of electron capture to alpha decay was
