9413067 Peterson Description: This project supports a U.S. scientist to travel to Pakistan and collaborate with scientists there on Pion-induced breakup detection using track detectors. Fragments of nuclei after reactions with energetic pi mesons will be measured with a reliable and efficient detector system that requires a very time- consuming and careful analysis. The exposure to the requisite pion beams will be carried out in an optimal manner, in coordination with skilled analysts in Pakistan. The nuclear excitation energy will be at levels where traditional nuclear fission is preempted by fast fragment production. Nuclear targets of middle mass will be selected to minimize the role of fission in its traditional sense. Scope: The project involves Dr. R.J. Peterson, from the Nuclear Physics Laboratory at the University of Colorado, in Boulder, and a Pakistani team headed by Dr. Hameed Ahmed Khan, of the Solid State Nuclear Track Detector Laboratory in PINSTECH, Rawalpindi, Pakistan. The proposed work is part of a U.S.-Brazil- Pakistan collaboration in the study of pion- induced fission. Past collaboration has resulted in U.S. publication using data from Pakistan and calculations from Boulder. This grant is the first for the P.I. for the purpose of enhancing this collaboration, and it meets the criteria of the Division of International Programs. ***

小行星9413067 产品描述：该项目支持一名美国科学家前往巴基斯坦，并与那里的科学家合作，使用轨道探测器探测π介子引起的分裂。 与高能π介子反应后的原子核碎片将用可靠和有效的探测器系统测量，这需要非常耗时和仔细的分析。 将与巴基斯坦的熟练分析人员协调，以最佳方式进行必要的π介子束照射。 核激发能将处于传统核裂变被快速碎片产生所抢占的水平。 将选择中等质量的核目标，以尽量减少传统意义上的裂变作用。 适用范围：该项目的参与者包括博尔德市科罗拉多大学核物理实验室的R. J. Peterson博士和巴基斯坦拉瓦尔平迪Pengyech固态核径迹探测器实验室的Hameed Ahmed Khan博士领导的一个巴基斯坦小组。 拟议的工作是美国的一部分-巴西-巴基斯坦合作研究π介子诱发裂变。 过去的合作导致美国使用来自巴基斯坦的数据和博尔德的计算进行出版。这是P.I.的第一笔赠款。为了加强这种合作的目的，它符合国际项目司的标准。 ***
