Anapole Moment Studies in Francium

这种弱力导致了太阳周期的开始，将质子转化为中子，从而产生氦。与其他自然力相反的弱力，在不同的坐标系下观察是不一样的；这意味着它不守恒宇称，这给了我们一个独特的符号来表示它。本研究计划将研究原子核组成部分之间的弱相互作用，因为它在原子性质的宇称不守恒中表现出来。实验涉及到最重的碱原子：钫，以确保原子核中有大量的质子和中子，以及了解和操纵原子性质的可能性。测量策略需要使用TRIUMF加速器在线对激光冷却和捕获的钫原子进行微波光谱分析。同位素链的结果将扩大我们对原子核中弱相互作用的理解。这项研究将在核物理与原子、分子和光学物理之间的边界的两名研究生的帮助下进行。这是将在加拿大温哥华的TRIUMF举行的国际合作的一部分。本科生将在学年和夏季参与研究工作。国际合作包括与墨西哥社会经济学院联合开展的本科生研究项目。

The weak force is responsible for the beginning of the solar cycle, the conversion of protons into neutrons that then allow the production of Helium. The weak force, contrary to the other forces of nature, is not the same when viewed with different systems of coordinates; this means that it does not conserve parity, giving us a unique signature for its manifestation. This research program will study the weak interactions among the components of the nucleus as it manifests itself in parity non conservation on atomic properties. The experiment involves the heaviest alkali atom: francium, to ensure a large number of protons and neutrons in the nucleus, as well as the possibility to understand and manipulate the atomic properties of the atom. The strategy for measurement requires microwave spectroscopy of laser-cooled and trapped francium atoms on-line with TRIUMF accelerator. The results with a chain of isotopes will broaden our understanding of the weak interaction in the nucleus.The research will be carried with the help of two graduate students in the boundary between Nuclear Physics and Atomic Molecular and Optical Physics. This is part of an international collaboration that will take place at TRIUMF in Vancouver, Canada. Undergraduates will participate in the research effort during the academic year, and in the summer. International collaborations include a program for undergraduate research in conjunction with the Sociedad Mexicana de Fisica.
