Abstract

We show that the distribution of observed energies of GRB with known redshifts can be explained by the hypothesis of the standard energy release E0=5 1051 ergs. Two situations are possible, either the beaming angle differs from burst to burst, or there is a universal emssion diagram in each burst, the observed difference being due to different viewing angles.
