Abstract
A prototype Xe + 10% CH4 microstrip detector was used to study the K-e dge discontinuity in the pulse-height distribution as a function of th e energy of incident X-rays, The electronics used was such that a puls e-shape rejection could be made of K-fluorescence reabsorption in the detector, The measured jump at the K-edge was (169 +/- 12)eV. It was a lso seen that K-alpha- and K-beta-decay channels produce different pul se heights for the same deposited energy. We find that the difference in energy between the calibration fines of the K-beta 2- and the K-bet a 1.3-escape peaks is (93+/-12)eV whereas between the K-beta 1.3 and t he K-alpha-escape peaks' calibration tile energy gal? is (69+/-7)eV.
