E0 andM1 excitations in56Ni

Abstract

The centroid energy and the decay width of the giant monopole resonance in the unstable nucleus56Ni are predicted. The resulting 0+, ΔT=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 theM1 response in this nucleus which shows a strong isovector transition at 9.6 MeV and a weak isoscalar one at 7.5 MeV.
