SAM revisited: absorptive uniform semiclassical approximation and application to heavy-ion elastic scattering

Description

The Uniform Semiclassical Approximation is modified to take into account absorption. Symbol calculus and pseudodifferential operators techniques are employed for the purpose. The resulting theory, very similar to the one developed by Frahn and Gross permits the decomposition of the near-side and far-side amplitudes into diffractive and refractive components. Application to several heavy-ion systems at intermediate energies is made. (author)

Abstract (Portuguese)

A aproximacao semiclassica uniforme e modificada para levar em conta a absorcao. Tecnicas de calculo de simbolos e operadores pseudodiferenciais sao usadas para a proposta. A teoria resultante, muito similar ao desenvolvimento por Frahn e Gross permite a decomposicao de amplitudes proximas e afastadas em camponentes difrativas e refrativas. Aplicacao a varios sistemas de ions pesados a energia intermediarias sao feitas. (M.C.K.)
