In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, ...

An international research collaboration led by the University of Surrey's Nuclear Physics Group has overturned the long-standing belief that the atomic nucleus of lead-208 (²⁰⁸Pb) is perfectly ...

Nuclear and plasma physics form complementary pillars in our understanding of the fundamental forces and states of matter. Nuclear physics investigates the structure, dynamics and interactions of ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

The liquid-fueled molten salt reactors such as the MSRE and the TMSR-LF have distinguishing dynamic features compared with solid-fueled reactors, such that conventional system analysis codes are not ...
