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 ...

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 ...

Predicted α-decay chain of new element 119 isotopes (²⁹³,²⁹⁴119), highlighting several as-yet-undiscovered nuclei. The proposed use of ⁴⁰Ar beams offers a promising approach for synthesizing key ...
