De velopment of the RAON recoil spectrometer (KOBRA) and its applications for nuclear astrophysics

KOBRA (KOrea Broad acceptance Recoil spectrometer and Apparatus), a new generation recoil spectrometer, has been designed at the Korean heavy-ion accelerator facility, so called RAON. It will allow many nuclear scientists to explore so-far hard but very interesting questions relevant to lowenergy nuclear physics. Especially, in nuclear astrophysics where the unstable, short-lived nuclei are usually involved and the high background rejection power is required, its high performance will come into significantly important role. As a particular case to see its capability, in this article, calculational results of 12C(α, γ)16O reaction which was studied with the COSY-INFINITY is presented.
