#### The statement of the problem of **scattering** of band electrons in an atomic chain by impurities in the approximation of potentials of zero radius

In this work the problem of electron bound to 3d linear atom chain **scattering** on impurity atoms is considered. In order to describe zone electrons the Bloch functions are constructed with respect to symmetry consideration. In addition, zero range potential approximation is used to model both atoms in chain and impurity ...

#### Numerical solving the problem of detecting of ultraweak diffractors in a complex acoustical medium

... in a complex acoustical medium are represented. The term “ultraweak” here means that the diffractors are not determined by standard depth migration. To solve the problem of detecting we use two procedures: Reverse Time Datuming (RTD) and Common **Scattering** Point (CSP). The first procedure (RTD) extends (synthetic) wave field from the day surface down to some level that is sufficiently close to diffractors. Then the diffractors are determined by CSP-method. The numerical model of an acoustical ...
