Source sentences:
text: Most odd–odd nuclei are highly unstable with respect to beta decay, because the decay products are even–even, and are therefore more strongly bound, due to nuclear pairing effects.
text: If the proton manages to be "captured" in the nucleus of a lithium atom, the resulting nucleus is unstable, and breaks into alpha particles.
text: Some atomic nuclei are unstable because the binding force varies for different atoms based on the size of the nucleus.
text: Therefore, the s-process takes a more or less clear path: for example, stable cadmium-110 nuclei are successively bombarded by free neutrons inside a star until they form cadmium-115 nuclei which are unstable and decay to form indium-115 (which is nearly stable, with a half-life 30000 times the age of the universe).
text: An atom that gives off radiation has an unstable nucleus; in many cases this means it has too many neutrons.
