Here I have a problem:

A 232/92 Uranium nucleus emits an alpha particle with kinetic energy=5.32MeV. What is the final nucleus and what is the approximate mass(in units) of the final atom.

I can write the equation for the reaction, this will give 4/2 He and 228/90 Th. If the alpha particle has KE=5.32MeV then is this the energy emitted in the reaction? If this is then I can obtain the change in mass. Is this correct? Any help is welcomed, thx. Joe
