D030000100008 cyclotron, using 9.6-MeV protons. D030000100009 METHOD (EXTB) The polarization measurements were made by mean D030000100010 double-scattering technique in which a copper foil was D030000100011 used for the first target and helium gas was used for D030000100012 the second target. D030000100013 The polarimeter contained helium gas at a pressure of D030000100014 10 atm, with windows of 0.002-in.-thick Mylar foil. D030000100015 SAMPLE Natural copper target of spectroscopic purity with a D030000100016 thickness equivalent to 390 keV for the incident D030000100017 proton beam. D030000100018 DETECTOR (TELES,PROPC,CSICR) The double-scattered protons were D030000100019 detected with counter telescopes, each consisting of a D030000100020 proportional counter and a scintillation counter. D030000100021 A multi wire proportional counter was used as a D030000100022 flow-counter with an argon (90%)-methane (10%) mixture D030000100023 which produced an energy loss of 200 keY for protons D030000100024 passing through it. The active volume of the counter D030000100025 was made small in order to reduce background. The D030000100026 scintillation crystal was a l-in.-diam Cs(Tl) crystal D030000100027 with a thickness slightly greater than the range of D030000100028 the doubly scattered protons.
