Predominant 7.7% impurity of Ca-40. D064100100025 The impurity of Ca-46 is less than 0.01%. D064100100026 DETECTOR (MCPLT,SIBAR,TELES) D064100100027 Two microchannel plate detectors (MCP1 and MCP2) and a D064100100028 450 mm2 silicon detector giving the energy (E) and D064100100029 the start signal used for the time-of-flights TOF1, D064100100030 TOF2, and triggering the data acquisition. D064100100031 The total length of the telescope was 40 cm with a D064100100032 geometrical solid angle of 0.076 msr. D064100100033 The efficiency of the MCP detectors for evaporation D064100100034 residues has been determined to be >98%. D064100100035 METHOD (TOF) Evaporation residues (ER) were detected by two D064100100036 microchannel plate detectors (MCP1 and MCP2), and D064100100037 finally stopped in the silicon detector giving the D064100100038 energy (E) and the start signal used for the time-of- D064100100039 flights TOF1, TOF2, and triggering the data D064100100040 acquisition. D064100100041 The E-TOF1 spectrum alone was sufficient to identify D064100100042 the ER. The complementary E-TOF2 spectrum was used as D064100100043 an independent condition to get rid of spurious eventsD064100100044 in E-TOF1 at lower energies. D064100100045 PART-DET (ER) An electrostatic deflector separated the recoilingD064100100046 evaporation residues (ER) from the transmitted beam D064100100047 and beam-like particles at 0 deg and at small angles. D064100100048 ANALYSIS (INTAD) ER angular distributions were measured at D064100100049 E(lab) = 101.0, 76.7, 72.2 MeV in the range -7 degree D064100100050 to +6 degree with steps of 1 degree. D064100100051 CORRECTION Corrections were applied for: D064100100052 - The beam energy losses in the targets. D064100100053 - The calcium isotopic enrichment. D064100100054 - The transmission of the electrostatic deflector D064100100055 T = 0.73 +/- 0.03 D064100100056 ERR-ANALYS (ERR-S) Statistical uncertainties D064100100057 (ERR-SYS) The absolute cross section scale is accurate D064100100058 within +/-7%, with contributions arising from the D064100100059 - geometrical solid angles (measured by placing an D064100100060 alpha-source at the target position); D064100100061 - the fits and integrations of the angular D064100100062 distributions; and D064100100063 - the transmission of the electrostatic deflector.
