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.
