Isoscalar dipole coherence at low energies and forbidden E1 strength
P. Papakonstantinou, V. Yu. Ponomarev, R. Roth +1
In 16O and 40Ca an isoscalar, low-energy dipole transition (IS-LED) exhausting approximately 4% of the isoscalar dipole (ISD) energy-weighted sum rule is experimentally known, but…
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…
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…
A microscopic investigation of the transition form factor in the region of collective multipole excitations of stable and unstable nuclei
P. Papakonstantinou, E. Mavrommatis, J. Wambach +1
We have used a self-consistent Skyrme-Hartree-Fock plus Continuum-RPA model to study the low-multipole response of stable and neutron/proton-rich Ni and Sn isotopes. We focus on th…
