Extraordinarily powerful light from gamma-ray bursts might help produce heavy elements from the outer shells of dying stars.

The protons and neutrons are paired and symmetrically arranged, resulting in a more spherical nucleus. Lead-208, with 82 protons and 126 neutrons, sits at the intersection of two magic numbers ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

EXPERIMENTS on the processes arising in thorium under neutron bombardment have shown that nuclear fission is induced only by fast neutrons of energies of about 2 Mev. or more. There exists also a ...

The results also represent a unique challenge to current theoretical models, which struggle to explain how these shapes can arise from complex interactions of the protons and neutrons which make up ...

However as the number of protons increases, more neutrons are needed to keep the nucleus stable, for example lead, lead-206 has 82 protons and has 124 neutrons.

which struggle to explain how these shapes can arise from complex interactions of the protons and neutrons which make up the gadolinium-150 nucleus. Dr. Esra Yuksel, lead theoretician on the paper ...
