Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of ...

Different isotopes are distinguished by the number of neutrons in the nucleus: helium-3 contains one neutron alongside the two protons, while the heavier helium-4 contains two neutrons.

"Our experiments with muonic helium-3 provide the most accurate value to date for the charge radius of this nucleus," says Randolf Pohl, who is also a member of the PRISMA + Cluster of Excellence ...

An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium-3 with unprecedented precision. The results are an important stress ...

The helium-3 that PSI physicist and ETH Zurich professor Antognini is using in the current experiment lacks not only a neutron in the nucleus, but also both electrons that orbit this nucleus.

This is where a radioactive form of strontium (strontium-94) absorbs an alpha particle (a helium nucleus), then emits a neutron and transforms into zirconium-97. The study has been published as an ...

This rare form of helium is called helium-3 because it has two protons and one neutron in its nucleus. Normal helium, which is 700,000 times more common than helium-3, is called helium-4 because ...

Scientists announce discovery of new antimatter nucleus. Using New York's Relativistic Heavy Ion Collider, astronomers also investigated why there is more matter than antimatter in the universe. ...

For the helium-4 nucleus, theorists had until recently perceived the alpha particle as an autonomous and independent system within which nucleons simply move away from each other when the nucleus ...
