在实验室用pp散射研究了大尺寸GSO（Ce）晶体和叠层GSO（Ce）光谱仪的光输出响应。能量为392 MeV。质子束由核物理研究中心（RCNP）提供。GSO（Ce）闪烁体谱仪由三块塑料板、两块立方体GSO（Ce）晶体和一块圆柱形GSO（Ce）晶体组成。立方体边长为43 mm，圆柱体直径为62 mm，长120 mm。在实验室中测量了H（p，2 p）散射质子在19.7 ° ~ 66.1 °范围内的12个角度的能谱。frame.立方体的结果，光输出和存款能量的关系被确定为161兆电子伏。用圆柱体的测量允许研究高达198 MeV的光输出。利用这些结果，在30至198 MeV的质子能量范围内确认了良好的线性。利用所确定的关系式，对GSO（Ce）的光输出进行了研究。已证实，在堆叠的GSO（Ce）的情况下，线性保持高达至少340 MeV。
Light output response of a large GSO(Ce) crystal and a stacked GSO(Ce) spectrometer was investigated by the use of pp scattering at a lab. Energy of 392 MeV. The proton beam was provided by the Research Center for Nuclear Physics (RCNP). A stacked GSO(Ce) scintillator spectrometer consisted of three plastic plates, two cubic GSO(Ce) crystals and a cylindrical GSO(Ce) crystal. The cubes have edge length of 43 mm and the cylinder of 62 mm in diameter and 120 mm long. Energy spectra of protons from H(p,2p) scattering were measured at 12 angles from 19.7 to 66.1 deg in lab. frame. With results for cubes, a relation of light output and deposit energy was determined up to 161 MeV. The measurement with the cylinder allowed to study the light output up to 198 MeV. With these results good linearity was confirmed in a proton energy range between 30 to 198 MeV. By the use of the relation determined presently, light output of the stacked GSO(Ce) was examined. It was confirmed that, in a case of stacked GSO(Ce), the linearity holds up to at least 340 MeV.
