NeutronC scattering near an Efimov state
M. T. Yamashita, T. Frederico, Lauro Tomio
The low-energy neutronC scattering in a neutron-neutron-core model is studied with large scattering lengths near the conditions for the appearance of an Efimov state. We sh…
Trajectory of virtual, bound and resonant Efimov states
M. T. Yamashita, T. Frederico, L. Tomio
The pole trajectory of Efimov states for a three-body system with unbound and bound is calculated using a zero-range Dirac- potential. It is showed that a three-…
Comment on "Efimov States and their Fano Resonances in a Neutron-Rich Nucleus"
M. T. Yamashita, T. Frederico, L. Tomio
By introducing a mass asymmetry in a non-Borromean three-body system, without changing the energy relations, the virtual state pole cannot move from the negative real axis of the c…
Structure of exotic three-body systems
T. Frederico, M. T. Yamashita, A. Delfino +1
The classification of large halos formed by two identical particles and a core is systematically addressed according to interparticle distances. The root-mean-square distances betw…
Neutron-neutron correlation in the halo dissociation of light exotic nuclei
M. T. Yamashita, T. Frederico, Lauro Tomio
We present model results for the two-halo-neutron correlation functions, , for the dissociation process of light exotic nuclei modelled as two neutrons and a core. A minimu…
A doorway to Borromean halo nuclei: the Samba configuration
M. T. Yamashita, T. Frederico, M. S. Hussein
We exploit the possibility of new configurations in three-body halo nuclei - Samba type - (the neutron-core form a bound system) as a doorway to Borromean systems. The nuclei $^{12…
