The transverse instability in a beam and the blow-up in its size caused by an electron cloud become increasingly important in high-intensity accelerators. The electron cloud builds up through beam-induced multipacting. We investigated the energy spectrum of an electron cloud with short bunch using particle simulation. A ''stop-band'' structure is found and a model is suggested to explain and to describe this phenomenon. The number of stop-bands depends only upon the beam (bunch spacing and intensity) and the radius of the vacuum pipe. The electron-energy spectrum provides useful information for understanding multipacting and measuring the electron's energy.
