Abstract.
The role of different continuum components in the weakly bound nucleus 6 He is studied by coupling unbound spd -waves of 5 He by means of simple pairing contact-delta interaction. The results of our previous investigations in a model space containing only p -waves showed the collective nature of the ground state and allowed the calculation of the electric quadrupole transitions. We extend this simple model by including also sd -continuum neutron states and we investigate the electric monopole, dipole and octupole response of the system for transitions to the continuum, discussing the contribution of different configurations.
