Resonances and final state interactions in the reaction pp->pK^+Lambda

A. Sibirtsev, J. Haidenbauer, H. -W. Hammer +1

A study of the strangeness production reaction pp->pK^+Lambda for excess energies of epsilon \le 150 MeV, accessible at high-luminosity accelerator facilities like COSY, is present…

Three-body continuum states on a Lagrange mesh

P. Descouvemont, E. M. Tursunov, D. Baye

Three-body continuum states are investigated with the hyperspherical method on a Lagrange mesh. The -matrix theory is used to treat the asymptotic behaviour of scattering wave f…

Analysis of the He decay into the continuum within a three-body model

E. M. Tursunov, D. Baye, P. Descouvemont

The beta-decay process of the He halo nucleus into the alpha+d continuum is studied in a three-body model. The He nucleus is described as an alpha+n+n system in hyperspheri…

Relation between widths of proton resonances and neutron asymptotic normalization coefficients in mirror states of light nuclei in a microscopic cluster model

N. K. Timofeyuk, P. Descouvemont

It has been suggested recently ({\it Phys. Rev. Lett.} 91, 232501 (2003)) that the widths of narrow proton resonances are related to neutron Asymptotic Normalization Coefficients (…

Global study of quadrupole correlation effects

M. Bender, G. F. Bertsch, P. -H. Heenen

We discuss the systematics of ground-state quadrupole correlations of binding energies and mean-square charge radii for all even-even nuclei, from O16 up to the superheavies, for w…

Study of hyperfine anomaly in Be within three-cluster model

Y. L. Parfenova, Ch. Leclercq-Willain

The study of the hyperfine (hfs) anomaly in neutron rich nuclei can give a very specific and unique way to study the neutron distribution and the clustering structure. We study the…

Asymptotic normalization coefficients for mirror virtual nucleon decays in a microscopic cluster model

N. K. Timofeyuk, P. Descouvemont

It has been suggested recently (Phys. Rev. Lett. 91, 232501 (2003)) that charge symmetry of nucleon-nucleon interactions relates the Asymptotic Normalization Coefficients (ANCs) of…

Microscopic models for exotic nuclei

M. Bender, P. -H. Heenen

Starting from successful self-consistent mean-field models, this paper discusses why and how to go beyond the mean field approximation. To include long-range correlations from fluc…

Analysis of fusion-fission dynamics by pre-scission neutron emission in Ni+Pb

Y. Aritomo, M. Ohta, T. Materna +3

We analyzed the experimental data of the pre-scission neutron multiplicity in connection with fission fragments in the reaction Ni+Pb at the incident energy correspo…

Hyperfine anomaly in Be isotopes in the cluster model and the neutron spatial distribution

Y. L. Parfenova, Ch. Leclercq-Willain

The study of the hyperfine anomaly of neutron rich nuclei, in particular, neutron halo nuclei, can give a very specific and unique way to measure their neutron distribution and con…

Comparative variational studies of states in three- models

E. M. Tursunov, D. Baye, P. Descouvemont

Three variational approaches, the hyperspherical-harmonics, Gaussian-basis and Lagrange-mesh methods involving different coordinate systems, are compared in studies of bound-…
