Abstract
A single line linear polarized source of 14.4 keV is realized in a conventi onal Mossbauer setup. In combination with the dichroism of a magnetized (Fe BO3)-Fe-57 or alpha-Fe-57 absorber a single line unpolarized Co-57<(Cr)unde r 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 op timal value of the internal magnetic held of each absorber is selected by t emperature adjustment. Calculations and measurements are in good agreement.
