Isobaric analog states

Isobaric analog states refer to nuclear states that have the same mass number (total number of protons and neutrons) but differ in their arrangement or type of nuclear particles, making them isotopes of one another. In these states, the nuclei can exhibit similar properties, such as energy levels or decay patterns, even if they are different elements or isotopes. Understanding these states is important in nuclear physics as they help clarify how nuclei interact and behave under different conditions, revealing insights into the fundamental forces that govern atomic structure.
