AUTHOR (N.L.SINGH, A.V.MOCHAN RAO, S.MUKHERJEE, R.UPADHYAY, R.K.JAIN, S.K.BOSE, L.CHATURVEDI, J.RAMA RAO) REFERENCE (J,JP/G,14,931,1988) INSTITUTE (3INDBHU) FACILITY (ISOCY,3INDIND) Variable Energy Cyclotron Center, Calcutta. METHOD (STTA) 2 Stacks were Used to Degrade the Alpha-Particle Energies from 75 to 30 MeV and from 50 to 10 MeV. (GSPEC) (ACTIV) Beam Currents of the Order of 200 Nano-Amperes Were Used, So That a Few Hours of Well Controlled Irradiation was Necessary. (EXTB) MONITOR (13-AL-27(A,X)11-NA-24-G,CUM,SIG,,,EVAL) Above 50MeV. (13-AL-27(A,X)11-NA-22,CUM,SIG,,,EVAL) Above 50 MeV. 29-Cu-65(A,2N)31-Ga-67,Ind,Sig,,,Eval) Below 50 MeV. DETECTOR (GELI) ERR-ANALYS (ERR-T) The Absolute Error For Each Measured Cross Section is Essentially Composed of Uncertainties in the Photopeak Area, Detection Efficiency, Uniformity of the Foil Thickness, Spectroscopic Data and the Monitor Cross Section. (EN-ERR) Data Point Reader Uncertainty. COMMENT - By Compiler - Any Information About Cooling Time and Decay Curves Measurements is Absent. HISTORY (19990604C) By F.C. (19990612U) Last checking has been done. (19990621A) DATE is corrected SAMPLE Spectroscopically-Pure (99.99%) Gold Foils of Weight 23 Milligrams/Cm**2. ADD-RES (COMP) Hibryd Model. Code Alice/85/300. STATUS (CURVE) By CAJAD.
