Large Odd-even Radius Staggering In The Very Light Platinum Isotopes From Laser Spectroscopy
1999
Laser spectroscopy measurements have been carried out on very-neutron-deficient platinum isotopes with the COMPLIS experimental setup. Using the ${5d}^{9}{6s}^{3}{D}_{3}\ensuremath{\rightarrow}{5d}^{9}{6p}^{3}{P}_{2}$ optical transition, hyperfine spectra of ${}^{182,181,180,179,178}\mathrm{Pt}$ and ${}^{183}{\mathrm{Pt}}^{m}$ were recorded for the first time. The variation of the mean square charge radius between these nuclei, the magnetic moments of the odd isotopes, and the quadrupole moment of ${}^{183}{\mathrm{Pt}}^{m}$ were thus measured. A large deformation change between ${}^{183}{\mathrm{Pt}}^{g}$ and ${}^{183}{\mathrm{Pt}}^{m},$ an odd-even staggering of the charge radius, and a d…
The Super-FRS Project at GSI
2002
The GSI projectile fragment separator FRS has demonstrated with many pioneering experiments the research potential of in-flight separators at relativistic energies. Although the present facility has contributed much to the progress in the field of nuclear structure physics, major improvements are desirable in the future. The characteristics of the proposed next-generation facility at GSI, the Super-FRS, will be presented and compared to other projects. The Super-FRS is a large-acceptance superconducting fragment separator followed by different experimental branches including a combination with a new storage-cooler ring system. This system consists of a collector ring (CR) and a new experime…
Susy for non-Hermitian Hamiltonians, with a view to coherent states
2020
We propose an extended version of supersymmetric quantum mechanics which can be useful if the Hamiltonian of the physical system under investigation is not Hermitian. The method is based on the use of two, in general different, superpotentials. Bi-coherent states of the Gazeau-Klauder type are constructed and their properties are analyzed. Some examples are also discussed, including an application to the Black-Scholes equation, one of the most important equations in Finance.
Cinema as locus theologicus: Popes in film (from Leo XIII till Benedict XVI)
2020
Bishops of Rome have been, since the dawn of the cinema, a subject interesting for filmmakers and important for the Church, as a source of information on the papacy. Numerous feature and documentary films presented biographies, activities or teaching of the Popes. But in the context of theology, we should not forget that a film – be it biographical, historical or telling merely a fictional story – can be regarded as a locus theologicus. However, fictionalised biographies of the Popes are not strictly historical films, neither are these films hagiographies, because the view of the Pope is taken from an external perspective, distant from the faith. Rather, it is a particular genre, which chal…

Jean-Michel Maulpoix: un lirismo de la finitud
2010
Adentrarse en Pas sur la neige es hacerlo en un nudo donde se entrecruzan las líneas fundamentales de este universo poético. La nieve con su intenso poder evocador, ya sea mediante observaciones, recuerdos, reflexiones o derivas metafóricas, lo recorre en todas direcciones. Nieve blanca como un sudario,ligada por lo tanto a la muerte, que es el signo por excelencia de la finitud. Blanca también como el papel, algo propicio para una mutua metaforización con la escritura y la poética que la sustenta. Nieve de los recuerdos de infancia, donde el sujeto lírico adquiere su precaria consistencia. Nieve silenciosa, como silenciosa es la pluma que escribe o también la muerte. Los detalles de la nie…

Book's Abstract. Non–human primates have been perceived and classified with different approaches according to different cultural and philosophical traditions throughout the centuries. This book contains contributions that illustrate various aspects of the development of non-human primate natural history, starting from the ancient Greek world, through the Renaissance and European expansion, to the rise of Darwinism and finally to the work of Italian, French, Spanish and Portuguese scholars of the 20th and 21th centuries, concluding with an original work regarding the role of images in primate taxonomy and conservation.
Tipologia, materiali e costruzione: i prospetti colonnati pubblici in Sicilia dall’età post-unitaria al ventennio fascista, tra reminiscenze archeolo…
2020
The paper analyses the debate in Sicily on the construction of the monumental colonnaded porticoes that characterise the facades of public edifices built on the island from the post- Unification period to the Fascist regime. The pronao of the Massimo Theatre in Palermo (from 1875) marks the climax of a cultural movement, which, for almost a century, was to associate the neo-Greek style with public buildings and the material of choice of Sicily’s church building tradition in a deterministic manner. Calcarenite was used to build the peristyles of the temples of the archaic and classical age, with imposing, tapered and grooved columns consisting of overlapping sections. In the Fascist period, …
