网页Lawrencium's most stable isotope, lawrencium-262, has a half-life of about 4 hours. It decays into nobelium-262 through electron capture, mendelevium-258 through alpha decay or through spontaneous fission. Since only tiny amounts of lawrencium have ever been produced, there are currently no uses for it outside of basic scientific research.
