We report a development of two kinds of position-sensitive γ -ray detectors using position-sensitive photomultiplier tubes (PS-PMT) for 2D-ACAR apparatus; (1) a 5mm thick, 50mm diameter Gd2SiO5 (GSO) single crystal disc coupled to a PS-PMT (Hamamatsu R2487), (2) an 2D-array of small Bi4Ge3O12 (BGO) crystal blocks of sizes 2.2mm × 2.2mm × 15mm (25 × 21 pieces in 2.4mm pitch) coupled to a PS-PMT (Hamamatsu R3941). We employed the type (2) for our new 2D-ACAR. The method of the analysis of the data obtained by the new apparatus and the results are reported.
