Stochastic theory of line shape. I. Nonsecular effects in the strong-collision model

摘要: Starting from a general stochastic-theory result in which the Hamiltonian is taken to jump at random between number of forms, due, for example, spin-spin or spin-lattice relaxation, we treat model matrix describes relaxation process. In this, it assumed that probability one state another does not depend on initial state. This simplifies calculations considerably and can be used study some physical cases. A specialization this yields simple closed-form expression line shape quite useful experimental situations.
