Born method

An air-borne method of exploration for ore deposits has been realized with the help of luminescence Lidar. Lidar embodies a high power UV laser and a coaxial telescope detection system installed aboard a helicopter. The laser yields pulses having a peak power of 0.4- 0.5 mj, a time delay of 1 ps, gate width of 1 ms, repetition rate of 30-50 Hz, and a wavelength varying from 275 up to 400 nm. The laser footprint is about 400-500 cm and the distance between the closest footprints about 1 m. The air-borne survey is carried out from an altitude of 50-75 m. Sensitivity is 0.2- 0.5% by exposed area for most minerals (Seigel and Robbins 1982 Seigel and Robbins 1985).

The most common approach to the solution of nonlinear electromagnetic inverse problems is based on linearization of the forward modeling operator. This approach has found wide practical application because of the ease of its implementation, the accessibility of software for linear inversion, and the speed of numerical calculations. Linearization uses the family of linear and nonlinear approximations based on the Born method, described in Chapter 9. 

The numerical solution of (10.130) and (10.131) follows the conventional logic of the iterative Born method. First, we solve (10.130) for [Pg.317]

DQA approximation in magnetotelluric inverse problem The DQA approximation is particularly suitable for constructing massive 3-D magnetotelluric inversion schemes, because of the low cost and simplicity of the expressions for forward modeling. In this section I discuss the implementation of the DQA approximation in MT inversion, following the paper by Hursan and Zhdanov, 2001. The main advantage of the QA method over the iterative Born method is that now...

A large number of publications deals with both classical and quantum theories of excitation and ionization by electron impact. The approximate Born method and the distorted wave method are most commonly used. 

The Born method is applied when the potential energy of colliding partners U can be considered as a small perturbation, i.e. when the kinetic energy of particles is sufficiently high. A strict treatment of this problem shows that the above suggestion is valid provided... 

The distorted wave method can be used at low values of the relative velocity u at which the Born approximation is inapplicable. Unlike the Born method, assuming that an electron is a free moving particle, the wave equations of the distorted wave method involve the mean energy of the atomic field acting on the electron before and after its collision with the atom. 

A simplification that one can use instead of treating the solvent explicitly is to incorporate the solvent contribution by modeling it as a continuous dielectric medium. Such implicit solvation methods are widely used to reduce the computational expense of a simulation. A popular choice is the generalized Born method a review of this method and case studies of its application are contained in Bashford et al. ...
