Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. But are the nuclei of atoms really round? Intuitively this shape makes sense and physicists believed it ...

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

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 ...

Some atoms are stable, while others seem to fall apart. Lead-208 will probably last forever, while the synthetic isotope technetium-99 exists for just hours. The difference lies in the structure of ...
