Abstract
A one-dimensional spin-1/2 dimerized linear antiferromagnetic Heisenbeg cha in is investigated basing on the continuum representation of the model Hami ltonian at zero temperature. The dependence of the energy gap and the energ y density of the ground state upon the distortion strength of the model is obtained. It is shown that there exists a pure power law behavior, which is close to the results predicted by other authors.
