There has been considerable debate among physicists over the last 15 years about conflicting measurements of the charge ...
The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the ...
Two extremely precise experiments agree with a previously shocking measurement of just how big the proton is, which may help ...
Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy's Thomas Jefferson National ...
Chemists reveal method for differentiating PCET mechanisms – a key step for steering fundamental energy conversion and redox catalysis processes. Redox reactions form the basis of many fundamental ...
Irradiating ammonia—which is made up of one nitrogen and three hydrogens—with ultraviolet light causes one hydrogen to dissociate from the ammonia. SLAC researchers used an ultrafast "electron camera" ...
