Radioactive decay

 

Abstract

The study of the  excited stateof molecules is one of the importent fields of quantum physics and chemistry. These studies are based on differential equations. Parameters such  as  energy levels, transition  rates  and  average  lifetimes  are  determined  during  the transition of a molecule from an excited state to its ground state. The excited state of a molecule is a state in which the energy level is increased by external influences. These states are not stable and the molecule transitions to the ground state after a certain period by emitting energy. Kinetic equations are used to calculate the average lifetime of the instability of the excited state by associating the molecule’s transition rate constant with time-dependent changes in the state. This is of great importance for the application of quantum mechanics and the theoretical justification of experimentally observed results.
