An Experimental Verification of the Theory of Compound Nucleus APS Journals The Theory
: Proposed by Niels Bohr, the theory suggested that a nuclear reaction occurs in two stages: the formation of a "compound nucleus" and its subsequent decay, with the decay being independent of how the nucleus was formed. The Verification : Ghoshal bombarded with alpha particles and with protons to form the same compound nucleus, The Result
: He demonstrated that the ratios of the cross-sections for different reaction products were identical for both paths, providing direct, undeniable evidence for Bohr's hypothesis.

The "story" of S. N. Ghoshal 's work is one of an academic bridge-builder who helped modernize physics education in post-independence India.
Born in 1923, Samir Nath Ghoshal pursued his PhD at UC Berkeley under Emilio Segrè (a Nobel co-winner for discovering the antiproton). This connection placed Ghoshal at the heart of the "golden age" of nuclear research, where he famously provided the first experimental verification of Bohr’s Theory of the Compound Nucleus in 1950—a major milestone in understanding how nuclei interact and transform. The Core Work: "Nuclear Physics"
Upon returning to India, Ghoshal dedicated his career to teaching at Presidency College, Calcutta, and later at Lucknow University. He noticed a massive gap between complex research papers and what students were being taught. To bridge this, he wrote his definitive textbook, Nuclear Physics , which remains a standard reference today. His work is characterized by its: Unlike pure theoretical texts, Ghoshal includes a practical
Experimental Foundation: Unlike purely theoretical texts, his work explicitly connects complex math with laboratory observations.
Breadth of Scope: The "pdf work" often sought by students covers 19 chapters, ranging from radioactive decay and nuclear models to high-energy cosmic rays and particle accelerators.
Accessibility: Reviewers from sites like Amazon India and Google Books often highlight it as one of the best "deep-dive" introductions for undergraduate and postgraduate students. Why It’s Still Popular Today NUCLEAR PHYSICS BY S N GHOSHAL
