The study is part of Henna Kokkonen's doctoral thesis. Credit: Tommi Sassi For the first time in almost 30 years, the heaviest nucleus decaying via proton emission has been measured. The previous ...

For the first time in more than thirty years, the heaviest nucleus decaying via proton emission has been measured. The previous similar breakthrough was achieved in 1996. The radioactive decay of ...

Known as “islands of inversion,” these regions are found among a sea of normal nuclei. Now, a new island may have been ...

Mirror magic: The "cores" of the exotic nuclei oxygen-22 and silicon-22 both resemble that of oxygen-16, with eight protons and eight neutrons. The neutron-rich oxygen isotope contains an additional ...

STAR scientists searched for signs of saturation in collisions of a proton (black) with a nucleus (multicolored). By tracking events where a pair of neutral pion particles (π0) strikes a forward ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

A researcher stands behind a metal pipe covered with electrical cords and gauges. A researcher works on a device at the Facility for Rare Isotope Beams. This part of the facility provides low-energy ...
