 note = {A tandem detector, which positively raises directional dependence for coming gamma-rays, has been developed for simultaneous measurement of directions and energies of coming gamma-rays. The detector has optically combined a cylindrical NaI(Tl), the same sized BGO scuntillator and a fitted photomultiplier tube at this order. Since lengths of crossing each scintillator are changed according to coming directions of gamma-rays, directions can be recognized by counting photopeaks on a spectrum made by the NaI(Tl) and the BGO scintillator and by obtaining the ratio of photopeak counts. It is also clear that energies can be easily measured, which are proportional to channels of photopeaks on the spectrum derived from the detector.},
