We propose an experiment to measure the nuclear charge radii of light elements with up to
20~ times higher accuracy. These are essential both for understanding nuclear physics at …

IN THE LAST TWENTY-FIVE YEARS, and especially in the last ten years, environmental
history in the United States has become a recog-nized field with a strong core of both …

In this article, we provide a review of the current state of the research on the nonlinear
electrodynamics of vacuum in the presence of strong electromagnetic fields. We discuss the …

Electronic $ K $ x rays emitted by muonic Ar atoms in the gas phase were observed using a
superconducting transition-edge-sensor microcalorimeter. The high-precision energy …

In this study, we successfully applied a transition-edge sensor (TES) spectrometer as a
detector for microbeam X-ray measurements from a synchrotron X-ray light source in the …

We, the QUARTET Collaboration, propose an experiment to measure the nuclear charge
radii of light elements with up to 20 times higher accuracy. These are essential both for …

General relativity (GR) postulates have been verified with high precision, yet our
understanding of how gravity interacts with matter fields remains incomplete. Various …

Arrays of microcalorimeters based on transition-edge sensors (TESs) are being actively
deployed to laboratories all over the world. A TES microcalorimeter array produces very …

The high-precision kaonic neon X-ray transitions measurement performed by the
SIDDHARTA-2 collaboration at the DA $\Phi $ NE collider is reported. Both the X-ray …

The x-ray spectroscopy of the muonic atom has attracted atomic, nuclear, and particle
physicists since its discovery. The properties of a muonic atom, such as its binding energy or …
