Five cells in one stack and Cu foils, D404800100015 8 micron, in between as monitor foils were irradiated. D404800100016 METHOD (ACTIV,EXTB,STTA,GSPEC,BCINT,MOSEP) D404800100017 excitation function was measured via the D404800100018 activation technique using stacked gas cell targets. D404800100019 irradiatin were done at 11.5, 14.5 And 18.0 MeV D404800100020 primary proton energies. Irradiation time varied D404800100021 betwee 1 and 2 hours, and the beam intensity between D404800100022 100 and 200 Na. D404800100023 the charge was collection in a faraday-cup and also D404800100024 was monitored by 63-Cu(p,2n)62-Zn, 63-Cu(p,n)63-Zn and D404800100025 65-Cu(p,n)65-Zn monitor reactions D404800100026 nuclear data were taken from E.Browne and R.B.FirestoneD404800100027 table of radioactive isotopes ed.V.S.Shirley, Wiley D404800100028 1986. There was 10 % difference between the two D404800100029 method of determining the beam current. In calculation D404800100030 of cross section the charge measured in Faraday cup wasD404800100031 used. D404800100032 the energy in the centre of each target cells was D404800100033 determined using Ziegler'S formula (handbook of D404800100034 stopping cross-sections for energetic ions in all D404800100035 elements, vol 5.,Pergamon press, Oxford 1980.)
