Classification of Decay Types

If Ey = 2 MeV, and A = 50, the recoil energy is about 40 eV, which is negligible except for Mossbauer studies (see later). 

Solution Recall that M0c2 = amu 931.5 MeV/amu. Using the mass defect of 68.417 MeV found in the Wallet Cards (see Appendix B), the mass of 69Zn is 68.297 amu. 

The conservation of angular momentum has provided an enormous amount of information on the structure of nuclei and plays a controlling role in the y-ray decay 

To understand the parity of electromagnetic transitions, we need to recall that each of the initial and final states of the nucleus undergoing the transition can be 

Example Problem Use the electromagnetic selection rules to identity the character of the crossover transitions that could link the second excited state at 2.080 MeV ( + ) in 23Na with the ground state ( 1 ).
