Nuclear collective excitations using correlated realistic interactions: the role of explicit RPA correlations
P. Papakonstantinou, R. Roth, N. Paar
We examine to which extent correlated realistic nucleon-nucleon interactions, derived within the Unitary Correlation Operator Method (UCOM), can describe nuclear collective motion…
Nuclear Structure in the UCOM Framework: From Realistic Interactions to Collective Excitations
R. Roth, H. Hergert, N. Paar +1
The Unitary Correlation Operator Method (UCOM) provides a means for nuclear structure calculations starting from realistic NN potentials. The dominant short-range central and tenso…
Collective multipole excitations based on correlated realistic nucleon-nucleon interactions
N. Paar, P. Papakonstantinou, H. Hergert +1
We investigate collective multipole excitations for closed shell nuclei from 16O to 208Pb using correlated realistic nucleon -nucleon interactions in the framework of the random ph…
Nuclear Structure and Response based on Correlated Realistic NN Interactions
P. Papakonstantinou, R. Roth, H. Hergert +1
Starting from the Argonne V18 nucleon-nucleon (NN) interaction and using the Unitary Correlation Operator Method, a correlated interaction v_UCOM has been constructed, which is sui…
Hartree-Fock and Many-Body Perturbation Theory with Correlated Realistic NN-Interactions
R. Roth, P. Papakonstantinou, N. Paar +3
We employ correlated realistic nucleon-nucleon interactions for the description of nuclear ground states throughout the nuclear chart within the Hartree-Fock approximation. The cru…
Low-energy dipole excitations towards the proton drip-line: doubly magic 48Ni
N. Paar, P. Papakonstantinou, V. Yu. Ponomarev +1
The properties of the low-energy dipole response are investigated for the proton-rich doubly magic nucleus Ni, in a comparative study of two microscopic models: fully self-c…
