An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium ...

A research team has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium-3 is ...

The wavelength of these yellow lines is directly related to the energy levels of the sodium atom, and in this way spectroscopy opens a window onto atomic structure. The study of the spectra of the two ...

An elusive structure ... the RIKEN Atomic, Molecular and Optical Physics Laboratory and his co-workers have isolated both water dimer ions by trapping them in tiny droplets of cold helium.

Structure, shape and composition are the basic parameters responsible for properties of nanoscale materials, distinguishing them from their bulk counterparts. To reveal these in three dimensions ...

allowing predictions for how atomic mass affects reaction rates to be put to the test. A helium atom consists of a nucleus containing two positively charged protons and two neutrons, encircled by ...
