The evolution of the traditional nuclear magic numbers away from the valley of stability is an active field of research. Experimental efforts focus on providing key spectroscopic information that will shed light into the structure of exotic nucl[...]![]()

Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Elsevier Science BV | 1996-08-15The propagation laws of the intensity moments of a laser beam through ABCD optical systems are generalized to include pure phase transmittances. This is done by representing the behaviour of such transmittances by means of a 4 x 4 matrix, hi, wh[...]![]()

Fernández Pérez, Luis Antonio ; Muñoz Sudupe, Antonio ; Ruiz Lorenzo, J. J. ; Tarancón, A. | Elsevier Science BV | 1995-04We propose a family of renormalization group transformations characterized by free parameters that may be tuned in order to reduce the truncation effects. As a check we test them in the three dimensional XY model. The Schwinger-Dyson equations a[...]![]()

Several optical arrangements using non-uniformly polarized fields are proposed for generating beams with spin and/or orbital angular momentum. By choosing adequately the input beam polarization and the characteristics of the different proposed s[...]![]()

Gaidarov, M. K. ; Moumene, I. ; Antonov, A. N. ; Kadrev, D. N. ; Sarriguren, P. ; Moya de Guerra, Elvira | Elsevier Science BV | 2020-12The neutron skin of nuclei is an important fundamental property, but its accurate measurement faces many challenges. Inspired by charge symmetry of nuclear forces, the neutron skin of a neutron-rich nucleus is related to the difference between t[...]![]()

Llanes Estrada, Felipe José ; Cotanch, Stephen R. ; Bicudo, Pedro J. ; Ribeiro, J. Emilio ; Szczepaniak, Adam | Elsevier Science BV | 2002-11-04Implementing many-body techniques successful in other fields, we report a glueball Regge trajectory emerging from diagonalizing a confining Coulomb gauge Hamiltonian for constituent gluons. Through a BCS vacuum ansatz and gap equation, the dress[...]![]()

Piquero Sanz, Gemma María ; Mejías Arias, Pedro Miguel ; Martínez Herrero, Rosario | Elsevier Science BV | 1994-02-15The beam quality parameter of gaussian fields propagating through axicons is investigated. A simple analytical formula is derived for the output quality parameter in terms of the input beam width, refractive index of the axicon material and the [...]![]()

The open string on the plane-wave limit of dSn × Sn with constant B2 and dilaton background fields is canonically quantized. This entails solving the classical equations of motion for the string, computing the symplectic form, and defining from [...]![]()

We examine the quark mass dependence of the pion vector form factor, particularly the curvature (mean quartic radius). We focus our study on the consequences of assuming that the coupling constant of the ? to pions, g??? , is largely independent[...]![]()

The quasi-free scattering reactions C-11(p, 2p) and C-10,C-11,C-12(p, pn) have been studied in inverse kinematics at beam energies of 300-400 MeV/u at the (RB)-B-3-LAND setup. The outgoing proton-proton and proton-neutron pairs were detected in [...]![]()

Sánchez Brea, Luis Miguel ; Alonso Fernández, José ; Bernabeu Martínez, Eusebio | Elsevier Science BV | 2004-06-01When a polychromatic light illuminates a grating, an achromatic and continuous self-imaging regime is produced, what means that Talbot planes are eliminated. In this work, we investigate the existence of this continuous regime for generalized gr[...]![]()

In this paper we study properties ofcertain fuzzy maps associated to a map, and we apply these properties to obtain results on quotient fuzzy topological spaces.![]()

Zong, Yi ; Franco Peláez, Francisco Javier ; Agapito Serrano, Juan Andrés ; Fernandes, Ana C. ; Marques, José G. | Elsevier Science BV | 2006-09-29This paper concentrates on the selection of radiation tolerant isolation amplifiers, which are suitable for the signal conditioners for cryogenic system in the Large Hadron Collider (LHC). The evolution and the results of different commercial is[...]
