摘要

This is called the degeneracy of the spin states. It is one of the constants of motion of the ensemble of particles that constitute the nucleus and as such is a fundamental nuclear quantity and its value can be used as a test against any special nuclear model or theory.nThis talk is primarily concerned with the solution of this experimental problem by a combination of particle detection techniques and atomic beams. The results have been successful in that in the last three years the spins of fifty-two unstable isotopes have been measured in our laboratories with half-lives ranging from 18 minutes to 25,000 years, covering a wide variety of elements from potassium to curium.
