B011400100012 ERR-ANALYS (DATA-ERR) The Errors of the Cross Sections Result B011400100013 Mainly from the Statistical Uncertainties in the B011400100014 Activity Measurements(15%), the Target Thickness (5%) B011400100015 And the Beam Flux Determination (10%). Additionally, B011400100016 The Errors were Taken Into Consideration Attributed to B011400100017 A Correction of the Cross Sections For the Recoil B011400100018 Catching Efficiency and Activity Build-Up from Cycles B011400100019 Before.

B011400100021 ADD-RES (RANGE) B011400100022 The Main Goal of the Work was the Investigation of B011400100023 Different Reaction Mechanisms by Determining the RecoilB011400100024 Energies. This was Achieved by Measuring the Range B011400100025 Of Recoils in Carbon Catcher Foils. Additionally the B011400100026 Recoil Energies were Determined by Measuring the B011400100027 Energy Loss of the Alpha-Particles Emitted by the B011400100028 Decaying Residues Due to Self-Absorption in the B011400100029 Catcher Foil.
