We report the 2018 self-consistent values of constants and conversion factors of physics and
chemistry recommended by the Committee on Data of the International Science Council …

Laser spectroscopy of muonic atoms has been recently used to probe properties of light
nuclei with unprecedented precision. We introduce nuclear effects in hydrogen-like atoms …

The deuteron is the simplest compound nucleus, composed of one proton and one neutron.
Deuteron properties such as the root-mean-square charge radius rd and the polarizability …

A new scalar boson which couples to the muon and proton can simultaneously solve the
proton radius puzzle and the muon anomalous magnetic moment discrepancy. Using a …

We give a pedagogical description of the method to extract the charge radii and Rydberg
constant from laser spectroscopy in regular hydrogen (H) and deuterium (D) atoms, that is …

We consider the impact of combining precision spectroscopic measurements made in
atomic hydrogen with similar measurements made in atomic deuterium on the search for …

The energy levels of hydrogen-like atomic systems are shifted slightly by the complex
structure of the nucleus, in particular by the finite size of the nucleus. These energy shifts are …

Precision spectroscopy of light muonic atoms provides unique information about the atomic
and nuclear structure of these systems and thus represents a way to access fundamental …

The measurement of the Lamb shift in muonic hydrogen and the subsequent emergence of
the proton radius puzzle have motivated an experimental campaign devoted to measuring …

The complete relativistic O (α 2) nuclear structure correction to the energy levels of ordinary
(electronic) and muonic hydrogenlike atoms is investigated. The elastic part of the nuclear …
