Signature inversion in semi-decoupled bands: Residual interaction between h9/2 protons and i13/2 neutrons
(Elsevier, 1997)
Semi-decoupled bands based on the πh9/2 ⊗ vi13/2 configuration are observed in 162Tm,164Tm and 174Ta. Spins assigned to these bands imply an inversion of the expected signature splitting, which is interpreted as being the ...

Boson-conserving one-nucleon transfer operator in the interacting boson model
(American Physical Society, 2002-03-01)
The boson-conserving one-nucleon transfer operator in the interacting boson model (IBM) is reanalyzed. Extra terms are added to the usual form used for that operator. These new terms change generalized seniority by ...

Finite-size effects on multibody neutrino exchange
(American Physical Society, 1998-10-01)
We use an effective Lagrangian to study the multibody massless neutrino exchange inside a finite neutron star. Following Schwinger, we show how the total interaction energy density is computed by comparing the values of ...

Dispersive spherical optical model of neutron scattering from 27 Al up to 250 MeV
(American Physical Society, 2002-03-01)
A spherical optical model potential (OMP) containing a dispersive term is used to fit the available experimental database of s(u) and sT for n127Al covering the energy range 0.1–250 MeV using relativistickinematics ...

Investigation of the 9Li + 2H → 8Li + t reaction at REX-ISOLDE
(Elsevier, 2006)
The one-neutron transfer reaction 9Li + 2H → 8Li + t has been investigated in an inverse kinematics experiment by bombarding a deuterated polypropylene target with a 2.36 MeV/u 9Li beam from the post-accelerator REX-ISOLDE ...

Dynamic effective potential for α-particle bound and quasibound states
(American Physical Society, 1996-09-01)
We exploit analytic properties of the optical potential for elastic scattering of α particles on nuclei to extract information on the effective interaction that should be used to describe the motion of a cluster of two ...

Study of 10Li via the 9Li(2H, p) reaction at REX-ISOLDE
(Elsevier, 2006)
The 9Li + 2H reaction has been investigated at 2.36 MeV/u at the REX-ISOLDE facility. In this Letter we focus on the 10Li + p channel which potentially holds spectroscopic information on the unbound nucleus 10Li. The ...

A Symmetry-Adapted Algebraic Approach to Molecular Spectroscopy
(Scielo, 1996)
We apply a symmetry-adapted algebraic model to the vibrational excitations in D_3h and T_d molecules. A systematic procedure is used to establish the relation between the algebraic and configuration space formulations. In ...

Molecular-dynamics ensembles: Fluctuations and correlations near the phase transitions
(American Institute of Physics Publising LLC, 1993)
Computer simulations of liquid and solid systems very close to the melting-freezing transition zone have been performed for the microcanonical, canonical, and isothermal-isobaric molecular-dynamics ensembles. Temperature, ...

Is the optical model valid for the scattering of exotic nuclei?
(American Institute of Physics, 2005)
The optical model, and its applications to elastic, inelastic and transfer reactions is reviewed. The applicability of the optical model to the collisions of exotic nuclei is discussed. The sensitivity of recent experimental ...
