摘要：

A novel technique for absolute calibration of a Mott polarimeter is described that make use of electrons of accurately known polarization obtained through chemiionization reactions involving spin polarized He(2 (3)S) metastable atoms. This technique has been used to calibrate a compact retarding-potential Mott polarimeter and values of the effective asymmetry (Sherman) function S(eff) are presented for both gold and thorium target foils under a variety of operating conditions.
