Title: Preparation, characterization, and decay of einsteinium(II) in the solid state

Preparation, characterization, and decay of einsteinium(II) in the solid state Samples of EsCl/sub 2/, EsBr/sub 2/, and EsI/sub 2/ have been prepared for the first time by reduction of the corresponding einsteinium trihalides with hydrogen gas at elevated temperatures. The three dihalides were characterized primarily by their absorption spectra. The products of the decay of EsX/sub 2/ samples held at ambient and liquid helium temperatures have been monitored by spectrophotometry. In all cases positive identification of the granddaughter, CfX/sub 2/, species has been made. No definite spectral evidence for the presence of the possible daughter products, BkX/sub 2/, has been obtained.
