| Transport integrals I n (Θ D /T) are reviewed with their applications in solid-state physics, molecular dynamics, and electron spin-lattice relaxation. Analytical approximations of I n for n=2--8 are proposed as applicable for computer fitting procedures in the range of the variable x=Θ D /T from 0.1 to 40. The results are applied for description of the spin--lattice relaxation data collected for Cu 2+ ions in triglycine sulphate and are compared with relaxation data for Cu 2+ and Mn 2+ in (NH 4 ) 2 Mg(SO 4 ) 2 ...6H 2 O. |
