摘要：
A single line linear polarized source of 14.4 keV is realized in a conventional Mossbauer setup. In combination with the dichroism of a magnetized (FeBO3)-Fe-57 or alpha-Fe-57 absorber a single line unpolarized Co-57<(Cr)under bar>- Or Co-57<(Pt)under bar>-source delivers greater than or equal to 90% linear polarized radiation and about 25% of its primary intensity. The optimal value of the internal magnetic field of each absorber is selected by temperature adjustment. Calculations and measurements are in good agreement.
