The Nuclear Spin-Response and Medium Modifications (Physics)

这一建议的物理重点是在核介质中核子-核子相互作用的修正，以及原子核的自旋响应。这项实验工作主要在TRIUMF设施进行。印第安纳大学回旋加速器设施正在寻求新的方向，以将TRIUMF工作扩展到200 MeV，布鲁克海文国家实验室正在超核物理计划中使用克子束。这一提议的主要焦点是继续现有的关于核的自旋响应的研究，目的是了解核介质中NN(核子-核子)力的自旋依赖性如何不同于自由空间中的NN力。

The physics emphasis of this proposal is on the modifica- tion of the nucleon-nucleon interaction in the presense of the nuclear medium, and on the spin-response of the nucleus. This experimental work is being done mainly at the TRIUMF facility. New directions are being pursued at the Indiana University Cyclotron Facility to extend the TRIUMF work to 200 MeV, and at Brookhaven National Laboratory using kaon beams in the hypernuclear physics program. The main focus of this proposal is to continue existing research into the spin-response of the nucleus, with the goal of understanding how the spin-dependence of the NN (nucleon-nucleon) force in the nuclear medium is different from the NN force in free space.
