This paper will describe some characteristics of relaxation processes related to the depth and the symmetry of the inner-shell hole. The discussion will be based mainly on a particular element, lanthanum, comparing the response of atomic La with that of La complexes and La metal.作者: Respond 時(shí)間: 2025-3-22 03:08
