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…
Continuum RPA study of the incoherent mu-e conversion rate and its spurious 1- admixture
P. Papakonstantinou, T. S. Kosmas, J. Wambach +1
The incoherent transition strength of the exotic mu-e conversion in the 208Pb nucleus is investigated by utilizing the Continuum RPA method, appropriate for the evaluation of the r…
Self-Consistent Description of Collective Excitations in the Unitary Correlation Operator Method
N. Paar, P. Papakonstantinou, R. Roth +1
The fully self-consistent Random Phase Approximation (RPA) is constructed within the Unitary Correlation Operator Method (UCOM), which describes the dominant interaction-induced sh…
The Effect of the Short-Range Correlations on the Generalized Momentum Distribution in Finite Nuclei
Ch. C. Moustakidis, P. Papakonstantinou, E. Mavrommatis
The effect of dynamical short-range correlations on the generalized momentum distribution in the case of , -closed shell nuclei is investigated by i…
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…
Test of modified BCS model at finite temperature
V. Yu. Ponomarev, A. I. Vdovin
A recently suggested modified BCS (MBCS) model has been studied at finite temperature. We show that this approach does not allow the existence of the normal (non-superfluid) phase…
Hadronic Matter is Soft
Ch. Hartnack, H. Oeschler, Joerg Aichelin
The stiffness of the hadronic equation of state has been extracted from the production rate of mesons in heavy ion collisions around 1 GeV incident energy. The data are b…
Collective excitations in the Unitary Correlation Operator Method and relativistic QRPA studies of exotic nuclei
N. Paar, P. Papakonstantinou, H. Hergert +1
The collective excitation phenomena in atomic nuclei are studied in two different formulations of the Random Phase Approximation (RPA): (i) RPA based on correlated realistic nucleo…
Low-momentum Hyperon-Nucleon Interactions
B. -J. Schaefer, M. Wagner, J. Wambach +2
We present a first exploratory study for hyperon-nucleon interactions using renormalization group techniques. The effective two-body low-momentum potential V_low-k is obtained by i…
Shell-model test of the rotational-model relation between static quadrupole moments Q(2^+_1), B(E2)'s, and orbital M1 transitions
S. J. Q. Robinson, L. Zamick, A. Escuderos +3
In this work, we examine critically the relation between orbital magnetic dipole (scissors mode) strength and quadrupole deformation properties. Assuming a simple K=0 ground state…
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…
Matrix Elements and Few-Body Calculations within the Unitary Correlation Operator Method
R. Roth, H. Hergert, P. Papakonstantinou +2
We employ the Unitary Correlation Operator Method (UCOM) to construct correlated, low-momentum matrix elements of realistic nucleon-nucleon interactions. The dominant short-range c…
The Proton Electric Pygmy Dipole Resonance
N. Paar, D. Vretenar, P. Ring
The evolution of the low-lying E1 strength in proton-rich nuclei is analyzed in the framework of the self-consistent relativistic Hartree-Bogoliubov (RHB) model and the relativisti…
