Nature has intrinsic handedness because of the weak interaction, but the difference between the left- and right-handed cases is barely discernible in atomic and nuclear interactions. Understanding its strength in nuclei is possible through measurements that require francium atoms so cold that they barely move. They show the effects of the handedness, from the anapole moment, when they are set to oscillate, and their frequency of oscillation changes with the handedness. The researchers will study the weak interaction, the force responsible for the beginning of the solar cycle, inside the francium nucleus. The atoms, made in the accelerator at TRIUMF Vancouver Canada, will be held on a laser trap, excited with microwaves and generate signals that show the handedness of nature.This international effort, with active participants from the USA, Canada, and Mexico, as well as Australia and China, is an example of multinational collaboration that is enabling investigations at the frontier of physics. The research will allow US graduate and undergraduate students to obtain valuable global perspectives in science, and be educated in the boundary between atomic molecular and optical physics and nuclear physics. In addition, undergraduates from Mexico, through a program with the Sociedad Mexicana de Fisica, will participate in the summer at TRIUMF. The recently commissioned Francium Trapping Facility at TRIUMF is available for visits by the general public.

大自然由于相互作用而具有固有的握力，但是在原子和核相互作用中，左手和右手案件之间的差异几乎无法辨别。通过测量需要太冷以至于几乎没有移动的测量，可以理解其在核中的强度。它们显示了手工瞬间的效果，当它们设置为振荡时，它们的振荡频率随着手的变化而变化。研究人员将研究弱核内部太阳周期开始的弱相互作用，这是负责太阳周期开始的力。在加拿大Triumf Vancouver的加速器中制造的原子将在激光陷阱上举行，对微波炉感到兴奋，并产生信号，表明自然界的手段，这是来自美国，加拿大，墨西哥，澳大利亚以及中国的积极参与者，以及澳大利亚和中国的积极参与者，是多功能协作的一个例子，是跨国协作的典范，是对物理效果的跨国协作进行了良好的研究。这项研究将使我们毕业和本科生能够获得科学方面有价值的全球观点，并在原子分子和光学物理与核物理学之间的边界进行教育。此外，来自墨西哥的大学生通过与墨西哥社会的计划，将参加夏天的夏季。最近在Triumf的最近受过委托的Francium陷阱设施可供公众访问。
