Twelve Ilford K-Z plates are held in a rigid geometry which allows simultaneous measurements of nuclear reaction at the angles of 15O, 30°, 45O, 60 , . . . and 1651. In this paper the determination of counting efficiency of the nuclear plate is described. A scheme of a numerical calculation for the counting efficiency is programed and carried out. AS a check measurements of efficiency are made by counting the number of n-particles on the nuclear plates from PO-210 source electro-plated on the target. The results are in good agreement with the calculated ones.application/pdf200726 bytesapplication/pdfzh-TWjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/20060927120012148624/1/0033.pdf
