Alpha decay represents a fundamental mode of radioactive disintegration wherein an unstable nucleus emits an alpha particle—a tightly bound cluster of two protons and two neutrons. This process not ...

Scientists refer to atomic nuclei as “quantum many-body systems” because they are formed by many particles (nucleons, which include neutrons and protons) that interact with each other in complex ways.

Discover the fascinating process of radioactive decay, where unstable atoms transform, releasing energy in the form of alpha, beta, and gamma emissions.

Elements that do not exist in nature—that have been created in a laboratory—are unstable. After hours or days of one element bombarding another with enough energy for both to fuse, the resulting new ...
