The isotope 12B5 having a mass 12.014 u undergoes beta decay to 12C6. 12C6 has an excited state of the nucleus 12C*6) at 4.041 MeV above its ground state. If 12B5 decays to 12C*6, The isotope 12B5 having a mass 12.014 u undergoes beta decay to 12C6. 12C6 has an excited state of the nucleus 12C*6) at 4.041 MeV above its ground state.
