    "abstract": "We investigate effects of finite core-spin in two-neutron halos in the\nthree-body model consisting of two neutrons and a core. The states in the\nneutron-core subsystem can then have an additional splitting due to the\ncoupling of the neutron and core spins. The connection between the structure of\nthe total system and the states of the neutron-core subsystem depends strongly\non this spin splitting. However, the spatial structure is essentially\nunchanged. The neutron momentum distribution in a nuclear dissociation reaction\nwill consist of a broad and a narrow distribution arising from the two spin\nsplit neutron-core virtual states. The large distance behavior is investigated\nand the conditions for the Efimov effect turn out to be more restrictive. The\nmagnetic moment is equal to the core-value independent of spin splitting and\nenergies of the neutron-core states. The excited states of opposite parity\ndepend strongly on the spin splitting. The parameters in our numerical examples\nare chosen to be appropriate for $^{11}$Li and $^{19}$B.",
