... (eg. [13–15]). However, this model gives rise to a ground state wave function which extends too much in conf gura- tion space and, consequently, to an overestimation of the coupling to the continuum states [16,17]. In ... See full document

... The experimental data have been analyzed and normal- ized to the beam fluxes extracted from the d(γ,n)p mea- surements. The data have also been corrected for detector efficiencies, but corrections for finite geometry and ... See full document

... It is of great interest to check whether such a LIT calculation is able to reproduce the correct low-energy cross section in presence of the Coulomb barrier. The LIT calculations, as described in Chapter 3.4, are ... See full document

... the Coulomb phase shift is obtained by increasing the distance of the screened Coulomb potential because the screened Coulomb potential converges to the Coulomb potential by increasing the ... See full document

... After the first application of the TDHF theory, much e ff ort has been devoted to overcoming this di ffi culty and to developing transport theories that are able to describe not only mean values but also fluctuations (for a ... See full document

... use charge-symmetric (CS) parameters for the quantities dominated by nuclear forces, but take into account the Coulomb differences in the resonant sub-systems. This CS approach clearly has more justification for the ... See full document

... The proton-neutron interaction is of particular interest in respect how collectivity emerges in nuclear many-body quantum systems. The quadrupole-quadrupole part of this interaction forms the lowest-lying ... See full document

... In the years following, Thomson proposed a model of the structure of the atom. The pursuit of the nature of these fundamental building blocks of matter was still ongoing. Researchers attempted to test Thomson’s proposed ... See full document

... The Hubbard-Stratonovitch (HS) transformation [1, 2] is a common tool in many areas of theoretical physics, ranging from condensed matter to nuclear physics [3, 4]. Though the basic idea—completing the square—is quite ... See full document

... As one can see both experiment and numerical simu- lations do not provide the coherent value of the ξ constant so it is difficult to judge the quality of the numerical es- timates provided by the ERG calculations. One ... See full document

... The construction of a DVR orthogonal on the angular grid for one angular variable is a solv- able problem if the choice of the grid points coincides with the nodes of the Gauss quadrature [15]. Different kinds of ... See full document

... In July, 1994, 7-year old Megan Kanka from New Jersey had been invited by Jesse Timmendequas, a 33-year-old landscaper who lived next door, to come into his house and pet his new puppy. She did. He strangled her ... See full document

... The study of scattering processes in few-body systems is a difficult task from both theoretical and com- putational points of view. This complexity originates from intricate asymptotic boundary conditions for ... See full document
