9515510 Benenson This U.S.-Brazil collaborative research project combines 6 U.S. nuclear physicists from Michigan State University, led by Walter Benenson, with 6 Brazilian collaborators from the University of Sao Paulo (Alex Szanto de Toledo), Federal Univ. of Rio de Janeiro (Carlos Bertulani), and the Federal Fluminense University (Nelson Carlin) to conduct 4 different collections of experiments. The four ambitious measurements involving radioactive nuclear beams are: coulomb disassociation of halo nuclei; astrophysical measurements of levels near the proton drip line and reaction rates of unstable nuclei; total cross section measurements as a function of mass and energy for several exotic nuclei; and measurements of the nuclear temperature of fragments from the 14N + 12C reaction. The first three experiments will be conducted at National Superconducting Cyclotron Laboratory (NSCL) at MSU and the last one at the University of Sao Paulo's Pelletron facility. The projected series of tests will make excellent use of the lower-energy facilities in Sao Paulo, where more beam time is available than would be possible in the US laboratories. The interactions produced by a group of leading nuclear physicists in the two countries should benefit the scientific community in both the U.S. and Brazil. Students and post doctoral researchers will also travel to Brazil as part of the research effort. ***

9515510 Benenson 这个美国-巴西合作研究项目由 Walter Benenson 领导的密歇根州立大学的 6 名美国核物理学家和来自圣保罗大学 (Alex Szanto de Toledo)、联邦大学 9515510 Benenson 的 6 名巴西合作者组成。里约热内卢大学 (Carlos Bertulani) 和联邦弗鲁米嫩塞大学 (Nelson Carlin) 进行了 4 组不同的实验。涉及放射性核束的四项雄心勃勃的测量是：晕核的库仑解离；对质子滴线附近的水平和不稳定原子核的反应速率进行天体物理测量；几个奇异核的总横截面测量作为质量和能量的函数；以及 14N + 12C 反应碎片的核温度测量。 前三个实验将在密歇根州立大学国家超导回旋加速器实验室 (NSCL) 进行，最后一个实验将在圣保罗大学的 Pelletron 设施进行。 预计的一系列测试将充分利用圣保罗的低能耗设施，那里的光束时间比美国实验室更长。 两国顶尖核物理学家的互动应该会让美国和巴西的科学界受益。作为研究工作的一部分，学生和博士后研究人员也将前往巴西。 ***
