A new milestone in nuclear physics has been achieved with the direct observation of three different deformations in the atomic nucleus of lead-190 (190 Pb). These deformations, associated with ...

T he atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to ...

The IAEA's NUCLEUS information resource portal provides access to over 100 scientific, technical and regulatory resources, including databases, applications, publications and training material. As it ...

A compact method of detecting neutrinos provides new tests of physics theories and could lead to new reactor-monitoring methods.

In simple terms, that assertion is correct, but for those with an expertise in the field, the longer answer to who did it ...

The relative charge of a nucleus is the same as its proton (atomic) number. Key fact: isotopes are forms of an element that have the same number of protons but different numbers of neutrons.

An element's atomic number defines it ... neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

A crucial component of this is understanding the behaviour of the electrons that surround the atomic nucleus; these dynamics dominate the way atoms and molecules interact with their environment.
