Applications of the Transport Integrals in Solid-State Physics and in Electron Spin Relaxation

Phonon spectrum, electron spin–lattice relaxation and spin–phonon coupling of Cu2+ ions in BaF2 crystal

“…0 e x x n ðe x À1Þ 2 dx is called transport integral and its numerical value [33] and analytical approximation [34] are published. Thus, a final form of temperature dependence of the spin-lattice relaxation rate appropriate for description of experimental data within the Debye model is…”
