Quantum electrodynamics (QED), the quantum field theory that describes the interaction between light and matter, is commonly regarded as the best-tested quantum theory in modern physics. However, this claim is mostly based on extremely precise studies performed in the domain of relatively low field strengths and light atoms and ions1–6. In the realm of very strong electromagnetic fields such as in the heaviest highly charged ions (with nuclear charge Z ≫ 1), QED calculations enter a qualitatively different, non-perturbative regime. Yet, the corresponding experimental studies are very challenging, and theoretical predictions are only partially tested. Here we present an experiment sensitive to higher-order QED effects and electron–electron interactions in the high-Z regime. This is achieved by using a multi-reference method based on Doppler-tuned X-ray emission from stored relativistic uranium ions with different charge states. The energy of the 1s1/22p3/2&
The Center for Legal Aid Support Services (CLASS) has ended a National Legal Aid Conference in Monrovia, adopting the exercise as an annual national event.
The Moroccan Embassy emphasized the significance of administrative autonomy as a catalyst for development, citing as an example the limited autonomy given to Jeju, at a symposium it hosted in Seoul on Friday. South Korea's southernmost island is a self-governing province, except for defense, diplomacy and judicial affairs. Moroccan Ambassador to Korea Chafik Rachadi referred Jeju as a successful example of admin.
