The dependence of two-level systems in disordered atomic chain on pressure,both positive and negative was studied numerically. The disorder was producedthrough the use of interatomic pair potentials having more than one energyminimum. It was found that there exists a correlation between the energyseparation of the minima of two-level systems Delta and the variation of thisseparation with pressure. The correlation may have either positive or negativesign, implying that the asymmetry of two-level systems may in average increaseor decrease with pressure depending on the interplay of different interactionsbetween atoms in disordered state. The values of Delta depend on the sign ofpressure.
