用0.8-1 GeV质子辐照197 Au、208 Pb和natU的核素产生：与其它实验和理论预测的比较
Nuclide Production in 197Au, 208Pb, and natU Irradiated with 0.8-1 GeV Protons: Comparison with other Experiments and with Theoretical Predictions
摘要：
使用ITEP质子同步加速器U10以1.0 GeV质子辐照同位素富集的208 Pb和natU薄靶，并以0.8 GeV质子辐照197 Au薄靶。使用直接光谱法与高分辨率Ge探测器测量了400多个产生的核素的截面。测量的截面进行了比较，在GSI获得类似的数据为1 GeV/核子208 Pb，1 GeV/核子238 U，和0.8 GeV/核子197 Au与氢靶相互作用的运动学逆反应，并与natPb和197 Au的1GeV和0.8 GeV质子辐照的GRR数据，分别。我们的结果平均比GSI数据高出约10%至20%。用LANL程序CEM 2k + GEM 2和LAQGSM+ GEM 2以及与GSI蒸发/裂变程序ABLA合并的列日INCL核内级联程序对测量数据进行了分析。
英文摘要：
The ITEP proton synchrotron U10 was used to irradiate isotopically-enriched 208Pb and natU thin targets with 1.0 GeV protons and 197Au thin targets with 0.8 GeV protons. More than 400 cross sections of the nuclides produced were measured using the direct spectrometry method with a high-resolution Ge detector. The measured cross sections are compared with similar data obtained at GSI for kinematically inverse reactions of 1 GeV/nucleon 208Pb, 1 GeV/nucleon 238U, and 0.8 GeV/nucleon 197Au interacting with a hydrogen target and with the ZSR data on natPb and 197Au irradiated with 1 and 0.8 GeV protons, respectively. Our results are on average ~ 10 to 20% higher than the GSI data. The measured data are analyzed with the LANL codes CEM2k+GEM2 and LAQGSM+GEM2 and with the INCL intranuclear cascade code from Liege merged with the GSI evaporation/fission code ABLA.
