Target and detection techniques for theN13(p,γ)14O reaction using radioactive ion beams:C13(p,γ)14N reaction as a test case

A feasibility study was undertaken for the measurement of the resonance at ${\mathit{E}}_{\mathit{r}}$=545 keV in the ${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$(p,γ${)}^{14}$O reaction, using intense radioactive ion beams. The analog resonance at ${\mathit{E}}_{\mathit{r}}$=512 keV in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(p,γ${)}^{14}$N was chosen as a test case, leading to improved knowledge of the resonance parameters. Thin- and thick-target yields were obtained with ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ beams on an extended gas target and a polyethylene foil, respectively. In addition, thin and thick targets of enriched ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ were irradiated with proton beams. Normalization problems arising with mixed ion beams ${(}^{13}$N${/}^{13}$C) are discussed.
