LSO(Lu$$_{2}$$SiO$$_{5}$$:Ce)シンチレータは陽電子放射断層撮影(PET: Positron Emission Tomography)などへの利用されているシンチレータであり、$$gamma$$線検出の効率が高い。このシンチレータを利用してNa-22を用いた陽電子消滅法,特に陽電子消滅寿命測定や運動量-寿命相関測定(AMOC)に適用し、検出効率を大幅に改善し、試料への照射効果などを低減した高精度な測定を実現することに成功した。

LSO(Lu$$_{2}$$SiO$$_{5}$$:Ce) scintillator is often used for PET (Positron Emission Tomography) because of the high efficiency of $$gamma$$-ray detection. By use of this scintillator, we succeeded to obtain high efficiency on the measurements of positron annihilation methods, such as positron annihilation lifetime measurement and age-momentum correlation measurement (AMOC). It can supply the smaller change of the sample during measurements caused by the positron irradiation effect.
