Role of virtual break-up of projectile in astrophysical fusion reactions [PDF]

open access: yes, 2003
We study the effect of virtual Coulomb break-up, commonly known as the dipole polarizability, of the deuteron projectile on the astrophysical fusion reaction 3He(d,p)4He.

Constraining the Skyrme effective interactions and the neutron skin thickness of nuclei using isospin diffusion data from heavy ion collisions [PDF]

open access: yes, 2006
Recent analysis of the isospin diffusion data from heavy-ion collisions based on an isospin- and momentum-dependent transport model with in-medium nucleon-nucleon cross sections has led to the extraction of a value of $L=88\pm 25$ MeV for the slope of ...

Almost “very strong” multilane turnpike effect in a non-stationary Gale economy with a temporary von Neumann equilibrium and price constraints

open access: yesEconomics and Business Review, 2020
Mathematical models of economic dynamics and growth are usually expressed in terms of differential equations/inclusions (in the case of continuous time) or difference equations/inclusions (if discrete time is assumed).3 This class of models includes von ...

Soft Dipole Modes in Neutron-rich Ni-isotopes in QRRPA [PDF]

open access: yes, 2004
The soft dipole modes in neutron rich even-even Ni-isotopes are investigated in the quasiparticle relativistic random phase approximation. We study the evolution of strengths distribution, centroid energies of dipole excitation in low-lying and normal ...

Polarization observables in the semiexclusive photoinduced three-body breakup of 3He [PDF]

open access: yes, 2005
The photon and 3He analyzing powers as well as spin correlation coefficients in the semiexclusive three-body photodisintegration of 3He are investigated for incoming photon laboratory energies E=12, 40 and 120 MeV.
