Unterstützung suchen und Hilfe annehmen. First of all, it gives a more satisfactory definition of . (see, for example, Section 1.1.7), and secondly by using explicitly the algebraic properties of the basis operators the calculations are often greatly simplified (see Section 2.5). The usefulness of this method depends on the choice of thefilial 发表于 2025-3-23 15:09:35
Gerhard Franz,Hildegard Koehlernsemble of atoms has been excited “instantaneously” at time t = 0. As usual, “instantaneous” implies that the excitation time is short compared to the mean lifetime of the excited states and any characteristic precession frequency (see Sections 3.5 and 4.7.1).GUMP 发表于 2025-3-23 19:55:56

Thomas Poehlke,Werner Heinz,Heino Stövernstructive examples of their utility. As the first example, we will show how . can be obtained from a determination of the Stokes parameters. In particular, we will consider the case of excitation of atoms by electron impact under the conditions described in Sections 3.5 and 4.6.吹气 发表于 2025-3-24 17:19:14
