Comment on "New modes of halo excitations in the 6He nucleus"

We try to explain the differences in the He-6 dipole strength function by B. V. Danilin ct al. [Phys. Rev. C 55, R577 (1997)] and A. Cobis, D. V. Fedorov, and A. S. Jensen [Phys.Rev. Lett. 79, 2411(1997)]. We perform the full basis calculation of the strength function with the same renormalized interaction as B. V. Danilin et al. and show that the size of the basis, needed for converged calculations of the 6He continuum spectrum, is much larger than that for the discrete spectrum. The renormalized interaction of B. V. Danilin ct al. therefore cannot be used for the continuum spectrum calculations with the same basis size as for the ground state. [S0556-2813(99)05001-3].
