Abstract
The spectrum of the low-lying magnetic dipole excitations known as sci ssors mode is computed for several deformed nuclei by diagonalizing a Hamiltonian of separable form in a space spanned by one and two micros copic phonon states. The phonons are computed in the random-phase appr oximation. The effect of the coupling between one and two phonon state s on the fragmentation of the M1 strength is analysed.
