Abstract
The low-lying energy spectrum of a spinning quantum chain in the criti cal region is calculated by using Lanczos method. According to conform al theory, the anomalous dimensions chi and the normalising factor zet a are obtained from the energy spectrum. Also a simple derivation of t he field theory of the model is given.
