In a Fast Rotating Atomic Nucleus the Rate of Rotation $\times$

question 1

Multiple Choice

In a fast rotating atomic nucleus the rate of rotation is related to the energy of the emitted gamma-ray according to the relationship "E_gamma = 2hf," where h = Planck's constant,and f = rotational frequency.Find the period of rotation that corresponds to an energy of 0.75 MeV.
