    "abstract": "We investigate the nuclear collective excitations of Wigner-Seitz cells\ncontaining nuclear clusters immersed in a gas of neutrons. This baryonic\nnon-uniform system is specific to the structure of inner crust matter of\nneutron stars. The collective excitations are studied in the framework of a\nspherical Hartree-Fock-Bogoliubov + Quasiparticle Random Phase Approximation,\nformulated in coordinate representation. The calculations are done for two\nrepresentative Wigner-Seitz cells with baryonic density equal to 0.02 fm$^{-3}$\nand 0.08 fm$^{-3}$. It is shown that the excitations with low multipolarities\nare concentrated almost entirely in one strongly collective mode which exhausts\na very large fraction of the energy-weighted sum rule. Since these collective\nmodes are located at very low energies compared to the giant resonances in\nstandard nuclei, they may affect significantly the specific heat of baryonic\ninner crust matter of neutron stars.",
