NUCLEAR PHYSICS For problems related to the binding energy of the nucleus: 1. Complete a table with the information given using a table of nuclear masses to determine the total mass of the constituent particles that make up the nucleus. 2. Determine the difference between the mass of the nucleus and the mass of the constituent particles. 3. Use Einstein's energymass equation to determine the binding energy. (Remember the conversion factor: 931 MeV/u) For questions related to a particular type of nuclear decay when the parent nucleus is known: 1. Identify whether the decay is alpha, beta, or gamma. 2. Write down the general equation for the particular type of decay. 3. Use the conservation laws to determine the atomic number and mass number of the daughter nucleus. 4. Use a periodic table to identify the daughter element. For problems related to the calculation of the disintegration energy of an alpha decay: 1. Use a table of nuclear masses to determine the mass of the parent nucleus, daughter nucleus, and alpha particle in atomic mass units. 2. Determine the difference between the mass of the parent nucleus and the mass of the daughter nucleus + alpha particle. Express this difference in atomic mass units. 3. Determine the disintegration energy by multiplying the mass difference expressed in atomic mass units by 931.5 MeV/u.
