Just as electrons can be excited inside an atom, neutrons and protons can be excited from their ground states into higher-energy states inside the nucleus. If these states have long half-lifes then th...

Governments that have signed the CTBT – which will come into force this September – are concerned that countries such as Iran, India and Iraq might try to develop so called ‘sub-crit...
Seaborg shared the 1951 Nobel Prize for Chemistry with the physicist Edwin McMillan. In addition to a long career at the University of California and the Lawrence Radiation Laboratory, both in Berkele...
Some researchers remain adamant that cold fusion is real, as David Voss reports
The existence of superheavy elements was predicted about 30 years ago on the basis of the nuclear shell model, which was originally developed in 1949. The model explains why nuclei with certain “...
Researchers at the Dubna Laboratory of Heavy Ion Nuclear Reactions in Russia, headed by Yuri Oganessian, collaborating with a team from the Lawrence Livermore National Laboratory in the US, made the d...
Donald Umstadter and co-workers used a neodymium-glass laser to illuminate helium gas in a vacuum chamber. The team were able to focus 4 trillion watts of power on the gas. The electric field of the l...
The UK at present has no nuclear physics facilities of its own, and very little investment in facilities overseas. “SIRIUS would open up many opportunities in a number of areas, most notably in ...
These latest results, according to Barker et al., indicate “high confidence” that the network being set up to monitor the CTBT can indeed verify small nuclear explosions. Concerns over the...
Bohr had escaped from German-occupied Denmark in September 1943 and crossed the Atlantic to work with British and American physicists on the Manhattan atomic-bomb project at Los Alamos. However, he re...
