Problem: The 7 Li nucleus has an excited state 0.48 MeV above the ground state. What wavelength gamma photon is emitted when the nucleus decays from the excited state to the ground state?

FREE Expert Solution

Energy is expressed as:

E=hcλ, where h is Plank's constant and c is the velocity of light in a vacuum. 

The energy of the nucleus is initially, E = 0.48 MeV = 0.48 × 106 eV
