Particle telescope consisting of two C249300100010 totally depleted silicon-surface-barrier transmission C249300100011 detectors. C249300100012 METHOD (EDE) Fission-fragment angular-distribution C249300100013 measurements were performed at alpha-particle C249300100014 energies of 27.5, 33.5, 43.8, 49.9, 58.9, 70.5, C249300100015 and 140 MeV for the alpha+233U system and at 69.2 and C249300100016 140 MeV for the alpha+209Bi system. Measurements were C249300100017 performed in ten-degree steps from 10 to 170 degrees. C249300100018 In addition, finer angular steps of 2 to 4 degrees C249300100019 were taken near 10, 90, and 170 to define the shape C249300100020 of the angular distribution in these regions. The C249300100021 fragment angular distributions were measured with a C249300100022 particle telescope consisting of two totally depleted C249300100023 silicon-surface-barrier transmission detectors (a 4 C249300100024 microm thick dE and a 25 microm thick E). C249300100025 ERR-ANALYS (DATA-ERR) No details on sources of uncertainties. C249300100026 (ERR-1) The integrated beam current (with an error of C249300100027 +-5% due to the absolute accuracy of the Faraday cup) C249300100028 was used for absolute normalization of the data.
