摘要：

The centroid energy and the decay width of the giant monopole resonance in the unstable nucleus Ni-56 are predicted. The resulting 0+, DELTA-T = 0 strength distribution, including the escape and the spreading width, displays a structure centered at around 18 MeV with the total width of about 5 MeV. We also study the M1 response in this nucleus which shows a strong isovector transition at 9.6 MeV and a weak isoscalar one at 7.5 MeV. PACS: 20.10. - k; 21.60. - n; 24.30. - v
