Abstract

A cross section measurement employing a direct ¹⁶O detection method for the reaction energies from E_cm = 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, a recoil mass separator and a RF-deflector. The measurements at E_cm = 2.4 and 1.5 MeV have been performed with these instruments. For measuring at E_cm < 1.2 MeV, a hybrid detector employing both, an ionization chamber and a silicon detector was developed to reduce the carbon backgrounds more efficiently. The oxygen ions were clearly separated from carbon background by using the energy deposit in the ionization chamber. Experiment of E_cm = 1.2 MeV was performed and the cross section was obtained.
