The di-neutron correlation is one of the most
interesting features of neutron-rich nuclei.
It is a manifestation of the strong coupling
pairing or the crossover between the conventional BCS
pairing and the Bose-Einsten condensation of composite
bosons, which is expected in halo, skin and neutron matter.
In this seminar talk, we present our Skyrme-HFB + QRPA
predictions on medium and heavy mass neutron-rich nuclei
to illustrate that the di-neutron correlation influences strongly
low-lying multipole excitation modes (dipole, quadrupole
and octupole). We also discuss its influence on
amplitudes of pair transfer processes, which may
provides us with experimental probes to the di-neutron correlation.
