1. The problem statement, all variables and given/known data At the other end of the nuclear size spectrum are the extremely large nuclei. Examine the reaction in which uranium fractures into cerium and zirconium: 235U -> 140Ce + 94Zr + neutron. Is this reaction allowed by energy considerations? If so, how much energy is released? Create each nucleus with the simulation, calculate its total binding energy, and find the net release of energy from the reaction. 2. Relevant equations NO IDEA 3. The attempt at a solution no IDEA.
