Abstract
ill model of the low-temperature orthorombic phase (O') of LaMnO3 was const ructed using pair potentials with explicitly allowing for the many-body Jah n-Teller contribution to the crystal energy. The analysis of the structure, elastic constants and phonon frequencies is based on the comparison of the structural phases that obtained with including and "switching-off" Jahn-Te ller contribution to the energy and dynamical matrix of the crystal.
