Cooper考虑一对电子在一个安稳的费米球面上相互作用着,指出这种相互作用是由声子和屏蔽库仑场导致的,在电子间存在一种净的吸引作用,结果这对电子能够形成一个束缚态.我们给出的是对于元素之中有化学键的形成,甚至电了发生了转移,电负性高的元素得到了电子,电负性低的元素失去了电子时退化费米气体中的束缚电子对的描述. Cooper considered a pair of electrons interacting on a stable Fermi sphere, pointing out that this interaction is caused by phonon and shielding Coulomb fields, and there is a net attraction between the electrons that results in the formation of electrons A bound state. We are given for the formation of chemical bonds among the elements, even the electricity has been transferred, the electronegativity of the high elements of the electron has been obtained, the electronegativity of the low elements of the electron-degenerated Fermi gas The description of the tethered electron pair.
