Drops of atoms with good angular-momentum quantum numbers

R Guardiola - Physical Review B, 2000 - APS
The stability of drops made of 3 He atoms is studied by means of a Monte Carlo variational
method using wave functions with good angular momentum quantum numbers. The number …

Alpha-cluster model for 8Be and 12C with correlated alpha particles

R Guardiola, I Moliner, MA Nagarajan - Nuclear Physics A, 2001 - Elsevier
An alpha-cluster model is proposed for 8Be and 12C nuclei, within the framework of the
resonating group method (RGM). The composing 4He clusters are described using Jastrow …

High-quality variational wave functions for small clusters

R Guardiola, M Portesi, J Navarro - Physical Review B, 1999 - APS
We report a variational calculation of ground state energies and radii of 4 He N droplets (3<~
N<~ 4 0), using the Aziz HFD-B (HE) atom-atom interaction. The trial wave function has a …

Central Jastrow and linear state-dependent correlations in nuclei

E Buendía, FJ Gálvez, J Praena… - Journal of Physics G …, 2000 - iopscience.iop.org
Linearized state-dependent and central Jastrow correlated trial wavefunctions are used to
study the ground state of spin-isospin saturated p-shell nuclei with V4-type forces. We …

Post-gaussian approximation to the soliton of the (1+ 1)-dimensional sine-gordon model

HG Kümmel - Physical Review B, 2001 - APS
Starting from the Gaussian-variational approximation the state of the single sine-Gordon

The nuclear Independent Particle model: A misunderstanding

MF de la Ripelle - Nuclear Physics A, 2010 - Elsevier
After quoting arguments against the validity of the nuclear Independent Particle model it is
shown that the magic numbers governing the structure of the nuclear ground states are …
