Molecular ion spectroscopy and mass measurements are critical areas of research in fundamental physics, particularly in understanding the interactions and properties of atomic and subatomic particles.

Development of two new techniques for studying the gas phase chemistry of negative ions is reported. Collision induced dissociation (CID) of ( M-1)- ions has been accomplished in a newly constructed ...

Using a new method, physicists have investigated the ultrafast fragmentation of hydrogen molecules in intense laser fields in detail. They used the rotation of the molecule triggered by a laser pulse ...

Researchers have clarified the crucial catalytic step in the production of hydrogen by enzymes. The enzymes, called [FeFe]-hydrogenases, efficiently turn electrons and protons into hydrogen. They are ...

High-precision measurements of the mass of the deuteron, the nucleus of heavy hydrogen, provide new insights into the reliability of fundamental quantities in atomic and nuclear physics. This is ...

According to a study published in Astronomy and Astrophysics, researchers from Max-Planck-Institut für Kernphysik (MPIK) in Heidelberg have uncovered fresh information on the reaction pathways of the ...

About 13.8 billion years ago, the newborn universe was a blazing sea of energy and particles. Within minutes of the Big Bang, conditions had cooled enough for the very first atoms—mostly hydrogen, ...
