Soft breathing modes in neutron-rich nuclei with the subtracted second random-phase approximation

NUCLEAR STRUCTURE ³⁴Si, ³⁶S, ^40,48,60Ca, ⁶⁸Ni; calculated isoscalar monopole excitations, strength distribution, neutron and proton transition densities, contributions from one-particle one-hole and two-particle two-hole configurations energy weighted sum rules (EWSR) using beyond mean-filed subtracted second random-phase approximation (SSRPA) based on Skyrme interaction SGII.
