Abstract

We present test calculations of the quasiparticle random-phase approximation with Skyrme and delta-pairing forces. We examine the convergence of solutions in the isoscalar 0⁺ channel as we increase the number of single-quasiparticle states, and the separation of spurious states from physical excited states in the isoscalar 1^- channel. Our calculation is fully self-consistent as it neglects no component of the interaction. We focus on Sn isotopes near the two-neutron drip line.
