TRIUMF travel for experiment S1107

Tigress Collaboration(与英国约克大学合作)投资于一种名为SHARC的紧凑型硅盒，它将在GE阵列内运行，并允许研究核子转移反应，从而打开了一个极好的新物理机会。ISAC-2光束的高光束质量和高强度很好地适应了传输研究，目前能量已达到4.5-5.0 MeV/A，其中微分截面的形状是传输角动量的特征，通过光学模型分析获得光谱因子是合理和证明的。萨里小组在SHARC的设计中发挥了重要作用，这将是利用这一新投资的第一个物理实验。这将是此类实验中的第一次，在这种实验中，使用伽马射线来分离所研究原子核中的各个状态是必不可少的，并利用了目前在TRIUMF的第一代放射束设施中可用的强钠束。这很可能是世界下一代辐射束设施实验的一个主要主题的先驱，这些设施刚刚建成。

An excellent new physics opportunity is opened up by the Tigress collaboration's investment (along with the University of York in the UK) in a compact silicon box called SHARC that will operate inside the Ge array, and allow the study of nucleon transfer reactions. The high beam quality and intensities of ISAC-2 beams are well adapted to transfer studies, and the energies have now reached 4.5 - 5.0 MeV/A, where the shapes of the differential cross sections are characteristic of the transferred angular momentum and the optical model analyses to obtain spectroscopic factors is reasonable and proven. The Surrey group played a prominent part in the design of SHARC and this will be the first physics experiment to exploit this new investment. The experiment will be the first of its type, in which the use of gamma-rays to isolate individual states in the studied nucleus is essential, and makes use of the intense sodium beams available at the present first-generation radioactive beam facility at TRIUMF. It is likely to be the forerunner of a major theme in experimentation at the world's next generation radioactive beam facilities, which are just now being constructed.
