D423900100015 Samples for irradiations were prepared by using the D423900100016 sedimentation technique onto 0.1 mm Al backing. D423900100017 Sediment layers were obtained, each having an enriched D423900100018 Se isotope content of 2.9-28.9 mg/cm2. D423900100019 DETECTOR (HPGE) D423900100020 METHOD (ACTIV,EDEG,EXTB,GSPEC,STTA) D423900100021 The induced radioactivity was measured non- D423900100022 destructively using HPGe detector gamma-ray D423900100023 spectrometry, analysing all major gamma-rays of the D423900100024 investigated radionuclides. D423900100025 Beam currents were measured in two different ways, D423900100026 involving current integration on the one hand, and D423900100027 the use of monitor reactions, on the other. D423900100028 Irradiations with protons up to an energy of 45 MeV D423900100029 were done at the injector cyclotron of COSY of the D423900100030 Forschungszentrum Julich, Germany. D423900100031 Irradiations in the higher energy region were carried D423900100032 out at the Separated Sector Cyclotron (SSC) of D423900100033 iThemba LABS in Somerset West, South Africa. D423900100034 The proton energy range covered by the irradiations D423900100035 was from 21 to 85MeV. D423900100036 The thin 77Se and 78Se targets were irradiated at D423900100037 both cyclotrons with protons of energies up to 66 MeV.D423900100038 The 80Se targets were irradiated with energies up to D423900100039 85 MeV. D423900100040 The formation of 80mBr was studied only in the lower D423900100041 energy range up to 19 MeV, utilizing the Compact D423900100042 Cyclotron CV 28 of the Forschungszentrum Julich. D423900100043 The energy ranges covered in the stacks were chosen D423900100044 such that they partly overlapped, thereby allowing a D423900100045 comparison of results in the overlapping regions, D423900100046 obtained in independent measurements. D423900100047 All obtained cross section values were normalised to D423900100048 100% enrichment of the respective target isotope.

D423900100057 (DATA-ERR) The total uncertainties of the measurements D423900100058 were calculated according to Gaussian error D423900100059 propagation. D423900100060 They are mainly based on the individual uncertainties D423900100061 of the incident proton energies, determination of D423900100062 particle flux and detector efficiency. D423900100063 Concerning the measurement of 80mBr, the efficiency D423900100064 calibration is less precise than in general, leading D423900100065 to higher uncertainties in those cross section data. D423900100066 Largely, the total uncertainty in cross section D423900100067 amounted to between 9 and 20%. D423900100068 ADD-RES (TTY-C) Integral yields were calculated from the D423900100069 fitted experimental cross sections.
