A further investigation of the nuclear scattering of 500-1000 MeV protons is described. Three-demensional information on the desity distribution within carbon, CH and H2O phantoms is obtained with a volume resolution of 2 mm3. The separation of scattering on hydrogen from that on heavier nuclei, such as carbon and oxygen, is demonstrated, providing the statistics are sufficient. Some preliminary measurements on animals are reported, but with a volume resolution limited by statistics to 43 mm3.
本文描述了对500-1000 MeV质子的核散射的进一步研究。利用2mm³的体积分辨率，获得了碳、CH和H₂O体模内密度分布的三维信息。结果表明，只要统计数据足够，就可以将氢上的散射与碳和氧等较重原子核上的散射区分开来。报告了一些对动物的初步测量结果，但由于统计数据的限制，体积分辨率为43mm³。
