Scientists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS), along with their collaborators, have recently discovered a molecular-type structure in the ground state ...

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, together with their collaborators, have achieved the first precise mass measurements of several exotic atomic ...

Keeping time is easy, keeping precise time is hard, but a new type of clock based on atomic nuclei has pushed time-keeping ...

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...

For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new ...

Findings in nuclear physics theory have received several Nobel Prizes (1975-nucleus vibrations and rotations, 1963-nuclear shell model, 1949-meson exchange model of nuclear forces). Despite these ...

An international research collaboration has overturned the long-standing belief that the atomic nucleus of lead-208 is perfectly spherical. The discovery challenges fundamental assumptions about ...

Benjamin Mottelson was a US-born physicist who specialized in theoretical work on the structure of the atomic nucleus. During the 1950s, in close collaboration with his Danish colleague Aage Bohr, ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

A schematic diagram of proton and neutron distributions for mirror nuclei argon-31 and aluminum-31. Left side is the weakly bound proton-rich nucleus argon-31, which is predicted to exhibit a ...
