Abstract

Based on the theory of unitary transformation and of SU（1‚1） Lie algebra‚the quantum size effect of ultrafine particle is discussed in detail in this paper∙T he energy eigenvalues of ultrafine particle are presented∙T hese solutions are of the time－dependent type∙

Keywords：ultrafine particle；quantum size effect；quantum mechanics
