Abstract
The Crab Pulsar (PSR B0531+21) was observed by the four Narrow Field I nstruments onboard the Italian-Dutch satellite BeppoSAX in August and September 1996, during the Science Verification Phase. The fine time r esolution (15 mu s) and high statistics provided phase histograms of v ery good quality over the entire energy band (0.1-300 keV) covered by BeppoSAX payload. In this letter we present a detailed study of the va riations in the light curve shape with energy and evaluate the spectra l index difference between the main features.
