When two kinds of ions with a very small mass difference are trapped at high density in the Fourier transform ion cyclotron resonance (PI-ICR) cell and are coherently rotating in their cyclotron orbits, collective motion of two ion packets takes place due to the Coulomb interaction and only one peak
