ResumoThe γ-ray detector CATANA (CAesium iodide array for γ-ray Transitions in Atomic Nuclei at high isospin Asymmetry) has been constructed to detect γ-rays from nuclear reaction with radioactive ion beams at RIKEN RIBF. CATANA consists of 100 square frustum-shaped CsI(Na) crystals coupled with photomultiplier tubes. The crystal shapes and positions are arranged to minimize the distance between the crystals so as to have better calorimetric properties and Doppler-shift correction capability. The CATANA array was employed to measure the dipole response of the neutron-rich calcium isotopes 50,52Ca, and the γ-rays from several known transitions were observed.
