A nucleus may be bound in a relatively high energy state, and if it can attain a lower energy, it will eventually do so. Nuclear Stability . Nuclear stability . means that nucleus is stable meaning . that it . does not spontaneously emit any kind of radioactivity (radiation). . On the other hand, . if the . nucleus is unstable (not stable), it has the tendency of emitting some kind of . low-temperature microcalorimeters. Some preliminary ideas and results. Michael W. Rabin.
