A general numerical solution of dispersion relations for the nuclear optical model
(IOP Publishing, 2001-07-16)
A general numerical solution of the dispersion integral relation between the real and the imaginary parts of the nuclear optical potential is presented. Fast convergence is achieved by means of the Gauss-Legendre integration ...

Is a global coupled-channel dispersive optical model potential for actinides feasible?
(American Physical Society, 2005-12-01)
An isospin-dependent coupled-channel optical model potential containing a dispersive term with a nonlocal contribution is used to simultaneously fit the available experimental database (including strength functions and ...

Neutron capture cross sections for the Re/Os clock
(AIP Publishing, 2005)
The radioactive decay of 187Re → 187Os (t 1/2 = 43 Gyr) is suited for dating the onset of heavy-element nucleosynthesis. The radiogenic contribution to the 187Os abundance is the difference between the natural abundance ...

The 139 La(n ,γ) cross section: Key for the onset of the s -process
(The American Physical Society, 2007)
The nuclear resonance parameters and the capture cross section of the neutron magic isotope La139 have been measured relative to Au197 in the energy range of 0.6 eV to 9 keV at the neutron time-of-flight (n_TOF) facility ...

A K = 3 two-quasiparticle isomer in 98 Sr
(American Physical Society, 2002)
The decay of on-line mass-separated 98 Rb to 98 Sr is studied by γ spectroscopy. The revised decay scheme adds further evidence of the coexistence of very different shapes in 98 Sr . A set of levels is ...

Neutron capture cross section measurements at n_TOF of Np-237, Pu-240 and Am-243 for the transmutation of nuclear waste
(AIP Publishing, 2006)
Accurate and reliable neutron capture cross section data for actinides are necessary for the proper design, safety regulation and precise performance assessment of transmutation devices such as Fast Critical Reactors or ...
