If the nuclei are infinitely far apart, then there is no interaction between them, and all that is measured is sum of their rest masses. When they are brought (not too) close together to form the nucleus, there is an attractive interaction between them. This is the same as saying that the potential energy of the system has been *reduced*. Therefore, the total energy of the nucleus (rest mass + potential energy) has been reduced. Because of the equivalence of mass and energy, this total energy is the apparent mass of the nucleus. -- Scott Anderson ihnp4!oddjob!kaos!sra
