O134900100004 AUTHOR (M.Crippa, E.Gadioli, P.Vergani, G.Ciavola, O134900100005 C.Marchetta, M.Bonardi) O134900100006 INSTITUTE (2ITYMIL) Department of Physics. O134900100007 (2ITYLNS) O134900100008 REFERENCE (J,ZP/A,350,121,1994) O134900100009 SAMPLE The Ta-181 targets, 800 and 1000-mug/cm**2 thick and O134900100010 Al-catchers 810-mug/cm**2 thick, downstream O134900100011 the targets, were used. O134900100012 REL-REF (M,,F.Fantoni+,J,ARI,45,325,1994) The experimental set-O134900100013 up. O134900100014 ADD-RES The analysis the excitation functions data of isotopes O134900100015 and isomers allows one to estimate the reaction cross O134900100016 section and the cross sections for complete fusion of O134900100017 C-12 and the incomplete fusion of Be-8 and alpha- O134900100018 fragments with tantalum. O134900100019 DETECTOR (HPGE) O134900100020 FACILITY (VDGT,2ITYLNS) O134900100021 METHOD (ACTIV) The irradiation times varied from 30 to 60 O134900100022 minutes at the various energies, according to the O134900100023 half-lives of the isotopes that were expected to be O134900100024 produced with the highest intensity. O134900100025 (GSPEC) Gamma ray activities were counted for several O134900100026 weeks. To reduce experimental errors authors analysed,O134900100027 when it was possible, up to four characteristic gamma O134900100028 lines for each isotope. The production cross section O134900100029 was then obtained as a weighted mean of the values O134900100030 deduced from the activity of each gamma ray. O134900100031 COMMENT -By authors. The cross section for cumulative O134900100032 production of a given residue is the sum of the cross O134900100033 section for its independent production and the cross O134900100034 sections for independent production of its precursors O134900100035 multiplied by numerical coefficients proportional to O134900100036 the branching ratio for the decay of the precursors to O134900100037 the residue and depending on the half-life of the O134900100038 precursors and the residue. O134900100039 ERR-ANALYS (ERR-T,10.,15.) The cross sections are usually affectedO134900100040 by an uncertainty varying from 10 to 15% mainly due to:O134900100041 * the statistical error in gamma-intensity, O134900100042 * the uncertainty in the background subtraction, O134900100043 * the uncertainty in the detector dead time, O134900100044 usualy a few percent all together; O134900100045 (ERR-1) the uncertainty in target thickness due O134900100046 to local thickness disuniformities approx.5%; O134900100047 (ERR-2,,5.) the uncertainty in the beam fluence <5%; O134900100048 (ERR-3,,10.) the uncertainty in the abundance of the O134900100049 residue characteristic gamma lines usually < 10%. O134900100050 In a few cases the abundances are known with an O134900100051 uncertainty much greater than that given above. O134900100052 STATUS (TABLE) Tables from Z.Phys.
