# MOSPLV, a program for simulation of complex Mössbauer spectra in polycrystalline samples

## Description

Abstract MOSPLV is a program written with the aim of calculating hyperfine Mössbauer spectroscopy patterns for polycrystalline samples in the effective field approximation for any possible static interactions. It includes calculation and solution of the full hyperfine Hamiltonian and calculation of the relative transition intensities, without other approximation than the effective field. It is designed specially to simulate spectra in the case of hyperfine Hamiltonians non-diagonal in the standard nuc... Title of program: MOSPLV Catalogue Id: ABTH_v1_0 Nature of problem In some cases, even if only static interactions are involved, Mossbauer spectra are not easy to analyse precisely and rapidly. The classical approximations do not always apply when the hyperfine hamiltonians cannot be expressed in a diagonal form for the standard angular momentum nuclear states. The main problem is to calculate the intensities of transition. Although the mathematical expressions are not very complicated, computing them exactly without approximation needs time and memory size. Th ...
