Nuclear physics is the study of the nucleus of an atom, which comprises protons and neutrons. The nucleus is the central part of an atom, making up most of its mass. The study of nuclear physics involves understanding the interactions between protons and neutrons within the nucleus, as well as the forces that hold them together.
S N Ghoshal is a distinguished Indian physicist who has made significant contributions to the field of nuclear physics. With a career spanning several decades, Ghoshal has worked on various aspects of nuclear physics, including nuclear reactions, nuclear spectroscopy, and nuclear models.
One of Ghoshal's most notable contributions is his work on the , a nuclear model used to describe the interaction between a nucleus and a projectile. The Optical Model is widely used in nuclear physics to study nuclear reactions and has been instrumental in shaping our understanding of nuclear phenomena.
