F069100100023 Effective reaction energies were determined from F069100100024 measurements of the target thickness and of the carbon F069100100025 buildup by consistent Rutherford backscattering F069100100026 measurements and (d,p) reaction analysis of 12C,16O F069100100027 performed many times during the course of the F069100100028 experiment.
