The influence of the lithium impurity on the formation and the stability of electronic colour centres is studied in NaF crystals. It is found that F- and M-absorption bands are somewhat displaced to the long wavelengthes when doping with lithium owing to the overlapping with FA- and MA-absorption bands. It is shown that the lithium impurity is stabilising one for the charged M-centres though their accumulation in the doped crystals occurs slower. The activation energy is determined for the thermal destruction of M+- centres. Thermal destruction of M+-centres assumed to be resulting from the anion vacancy removal. 相似文献

We consider a set of coupled underdamped ac-driven dynamical units exposed to a heat bath. The coupling scheme defines the absence/presence of certain symmetries, which in turn cause a nonzero/zero value of a mean dc-output. We discuss dynamical mechanisms of a dc-current appearance and identify current reversals with synchronization/desynchronization transitions in the collective ratchet's dynamics. 相似文献

A simple approach is proposed to describe the experimental data for the widths of the fission-fragment mass yields in~(197)Au and~(209)Bi at low and intermediate energies.The approach is based on the expressions for the temperature dependence of the width of the fission-fragment mass yield and the mass of the most probable fragment.The expression for the width of the fission-fragment mass yield depends on the mass of the most probable fragment,the surface terms of the energy level density parameter,the temperature and the stiffness parameter of the potential related to mass-asymmetric degree of freedom.It is shown that the contribution of the surface term of the energy level density parameter is important for describing the experimental data in a wide range of energies. 相似文献

We consider two inverse coefficient problems for a quasilinear hyperbolic equation, where the additional information used
for finding the coefficients is the values of the solution on some curve. (This corresponds to measurements performed at a
moving observation point.) The unknown coefficient depends on the space variable in the first inverse problem and on the solution
of the equation in the second inverse problem. We prove theorems of uniqueness of solution to the inverse problems. 相似文献

We consider numerical methods for solving inverse problems that arise in heart electrophysiology. The first inverse problem
is the Cauchy problem for the Laplace equation. Its solution algorithm is based on the Tikhonov regularization method and
the method of boundary integral equations. The second inverse problem is the problem of finding the discontinuity surface
of the coefficient of conductivity of a medium on the basis of the potential and its normal derivative given on the exterior
surface. For its numerical solution, we suggest a method based on the method of boundary integral equations and the assumption
on a special representation of the unknown surface. 相似文献
