D418200100011 Two stacks were irradiated, in one of the stacks Ni D418200100012 served as backing for electro-deposited Os used in a D418200100013 separate evaluation. D418200100014 METHOD (STTA,ACTIV,EXTB,GSPEC) D418200100015 Interleaved with the Ni or Os/Ni foils, Ti foils were D418200100016 inserted as monitor for determination of reliable beam D418200100017 characteristics (energy and intensity) and for checkingD418200100018 the energy degradation along the stack. The stacks wereD418200100019 irradiated in a Faraday-cup like target holder, D418200100020 equipped with a long collimator for precise definition D418200100021 of beam diameter and with a negatively polarized guard D418200100022 electrode to suppress secondary electrons. D418200100023 Incident deuteron energy: 20.5 MeV, D418200100024 beam intensity: 200 nA, D418200100025 irradiation time: 0.5 h. D418200100026 The count rate was in all cases low so that correctionsD418200100027 for pile up effects and dead time could be implemented D418200100028 through the acquisition and analyzing software. D418200100029 The charge on target was first derived from the D418200100030 Faraday-cup measurement. Adaptations in beam current D418200100031 and energy were made, based on parallel remeasuring of D418200100032 the excitation function for the monitor reaction over D418200100033 the whole energy region. D418200100034 DETECTOR (HPGE) D418200100035 MONITOR (22-TI-0(D,X)23-V-48,,SIG) D418200100036 MONIT-REF (D4081009,S.TAKACS+,J,NIM/B,174,235,2001) D418200100037 DECAY-DATA Decay data were taken from NUDAT2 database. D418200100038 ERR-ANALYS (EN-ERR) The uncertainty of the primary beam energy is D418200100039 0.2 MeV. The uncertainty on the average energy of the D418200100040 last foil of a stack, due to the uncertainty on the D418200100041 foil thickness and to energy degradation is estimated D418200100042 at 2.5 MeV. D418200100043 (ERR-T) For estimation of standard uncertainty on the D418200100044 cross section values the individual uncertainties D418200100045 included in the propagated error are: D418200100046 * number of target nuclei including D418200100047 non-uniformity (8%), D418200100048 * incident particle intensity (5%), D418200100049 * detection efficiency (5%), D418200100050 * peak areas including statistical errors (5-15%), D418200100051 * gamma decay data (1-5%). D418200100052 The total uncertainty of 10-20% is obtained as D418200100053 positive square root of a sum of the contributing D418200100054 sources in quadrature. D418200100055 The non-linear effects of the possible uncertainty of D418200100056 the half-lives were not taken into account. D418200100057 ADD-RES (COMP) The measured experimental data were compared D418200100058 with earlier literature values. D418200100059 (THEO) The predictive capability of the ALICE-IPPE, D418200100060 EMPIRE-II and GNASH model codes was tested. D418200100061 (TTY-C) Thick target yields were deduced from the D418200100062 experimental cross sections D418200100063 STATUS (APRVD) S. Takacs, 2007.05.31.

D418200200005 DECAY-DATA (29-CU-64,12.7HR,DG,1345.,0.0047) D418200200006 METHOD The larger statistical uncertainty due to the low D418200200007 intensity cannot be fully compensated by long D418200200008 measurement times as the limited half-life of 64Cu and D418200200009 the need to measure all foils of the stack preferably D418200200010 twice within two or three half-lives, puts a limit on D418200200011 the measurement time. The main advantage over the D418200200012 traditional assessment method (measuring the D418200200013 annihilation radiation) is the absence of interference D418200200014 and background signals.
