O143100100005 AUTHOR (A.Huke, K.Czerski, T.Dorsch, A.Biller, P.Heide, O143100100006 G.Ruprecht) O143100100007 INSTITUTE (2GERTUB) O143100100008 (3POLPOL) University of Szczecin. O143100100009 (1CANTMF) O143100100010 REFERENCE (J,EPJ/A,27,(S1),187,2006) O143100100011 SAMPLE The targets were pure metal disks becoming self- O143100100012 implanted deuterium targets under the deuteron O143100100013 irradiation. O143100100014 PART-DET (P,T,HE3) O143100100015 DETECTOR (SI) Four Si-detectors (surface barrier probably) with O143100100016 an active surface diameter of 1-cm at a distance of O143100100017 10-cm and the laboratory angles of 90, 100, 130 and O143100100018 150-degrees were used for the detection of all charged O143100100019 particles of the reactions H-2(d,p)t and H-2(d,n)He-3. O143100100020 Grounded Al-foils of thicknesses from 120-150 ug/cm2 O143100100021 were placed in front of the detectors insulated from O143100100022 them. The thickness is sufficient in order to stop O143100100023 backscattered deuterons up to 60 keV. The solid angles O143100100024 surveyed by the detectors were determined with a O143100100025 radioactive alpha-source. O143100100026 COMMENT *By authors*.The experimental results obtained for the O143100100027 transition metals Zr, Pd, Ta and also Al- do not differO143100100028 from those known from gas-target experiments, an O143100100029 enhancement of the angular anisotropy in the neutron O143100100030 channel and an attenuation of the neutron-proton O143100100031 branching ratio have been observed for the alkaline O143100100032 metals Li, Sr and Na at deuteron energies below 20-KeV.O143100100033 *By authors*the results for proton and tritons are O143100100034 concordant. The anisotropy data for Sr (in table) was O143100100035 renormalized to the ones of Ta. O143100100036 FACILITY (ACCEL,2GERTUB) The experiment has been carried out atO143100100037 an electrostatic cascade accelerator at beam energies O143100100038 below 60 keV maintained by a highly stabilized power O143100100039 supply. O143100100040 METHOD (BCINT) O143100100041 (SITA) See sample. O143100100042 (EXTB) The deuterium beam ions with final currents at O143100100043 the target < 200 uA depending on the energy. O143100100044 ERR-ANALYS Uncertainties in the integral of the spectral lines O143100100045 are taken into account in the errors additionally to O143100100046 the counting statistic. The problems of integrating theO143100100047 overlapping spectral lines cannot be circumvented by O143100100048 the use of detector telescopes for particle O143100100049 identification. The delta-E detector of the usual O143100100050 semiconductor detector telescopes would already absorb O143100100051 the recoil nuclei. O143100100052 Another problem affecting the results comes from a O143100100053 property of Rf-ion source inherent to their design.
