Scattering and Reactions of Intermediate Energy Projectiles (Physics)

将对下列基本问题进行研究： 在主要的核物理加速器上的核反应 这个国家和国外。 其中包括洛斯阿拉莫斯的LAMPF， 新墨西哥州，TRIUMF，在温哥华，加拿大，SATURNE II，在 法国萨克雷和瑞士日内瓦的LEAR。 他们最近 研究表明，细胞核出乎意料地接受 被来自射弹的自旋转移所激发， 射弹在散射中损失超过20兆电子伏 过程 他们将继续这项工作，以确定 许多核子的这种集体作用确实是一种普遍的 原子核在整个周期表中的特征。 他们将 继续研究π介子的吸收机制， 原子核。 π介子是核力的基本载体; 当它与中子或质子结合时， 粒子，三角洲。 研究人员还将探索 核关联似乎改变了质量的反应 细胞核内的δ。

Research will be conducted on fundamental problems in nuclear reactions at the major nuclear physics accelerators in this country and abroad. These include LAMPF, in Los Alamos, New Mexico, TRIUMF, in Vancouver, Canada, SATURNE II, in Saclay, France, and LEAR, in Geneva, Switzerland. Their recent work has shown that the nucleus is unexpectedly receptive to being excited by the transfer of spin from the projectile when the projectile loses more than about 20 MeV in the scattering process. They will continue this work to determine whether this collective action of many nucleons is truly a general feature of nuclei over the entire periodic table. They will pursue their investigations of pion absorption mechanisms in nuclei. The pion is the basic carrier of the nuclear force; when it combines with a neutron or proton, it can form another particle, the delta. The researchers will also explore reactions in which nuclear correlations seem to change the mass of the delta inside nuclei.
