| Research Abstract |
A cross section measurement employing a direct 16O detection method for the reaction energies from Ecm= 2.4 to 0.7 MeV is planned at Kyushu University Tandem Laboratory (KUTL).To perform this experiment and to obtain quantitative information about the cross section to within an error of 10%, we have developed several instruments, including a blow-in type windowless gas target and an ionization chamber.Experiments were performed at Ecm= 2.4 and 1.5 MeV using the developed instruments and the cross sections were obtained. A hybrid detector employing both an ionization chamber and a Si-SSD detector was developed to reduce the carbon backgrounds more efficiently. It was found that the new detector could reduce the background ratio by three orders,and the experiments in Ecm<1.2 MeV were ready for carrying out
