Recently,a mixture of superfluids of bosonic atoms and fermion pairs has been realized in ENS group and the collective excitation has been studied.In this system,one unique feature is that the boson mode of atoms will interact with both bosonic and fermionic mode of fermion superfluids,which leads to damping of collective excitations.We study two type of damping mechanisms,which valid at BCS side and BEC side of fermion superfluid,respectively,and find dramatic difference that is consistent with experiment.We also study the interaction energy between bosonic and fermionic superfluids.Atom-dimer scattering length is calculated and used as a calibration of mean-field approximation for this interaction energy.
