A lopsided atomic nucleus may help to refine nuclear theory. The stubby pear shape, described today in Nature, may also be pointing towards new tests of particle physics that could reveal why matter ...

An international team of physicists has found the best evidence yet that some heavy nuclei are not spherical or ellipsoidal – but “pear-shaped”. The researchers found clear signs of this lopsidedness ...

Atomic nuclei come in many shapes and sizes, and scientists have now obtained precise measurements of an elusive form: pear-shaped. Studying these exotic nuclei, which are described in the May 9 ...

Scientists have shown that some atomic nuclei can assume the shape of a pear which contributes to our understanding of nuclear structure and the underlying fundamental interactions. Scientists at the ...
