Probing 6He structure from proton inelastic collisions

We explore the Hyperspherical Harmonics pseudostate method to describe the 6He continuum. The method is use it within the multiple scattering of the transition amplitude (MST) approach to study inelastic scattering of p-6He at 700 MeV/u.Fundaçao para a Ciência e Tecnologia (FCT) POCTI/FNU/43421/200

Ru-Based Thin Film Temperature Sensor for Space Environments: Microfabrication and Characterization under Total Ionizing Dose

The paper shows the microfabrication processes of a Ruthenium-based resistance temperature detector and its behavior in response to irradiation at ambient temperature. The radiation test was done in a public hospital facility and followed the procedures based on the ESA specification ESCC 22900. The instrumentation system used for the test is detailed in the work describing the sensors resistance evolution before, during, and after the exposure. A total irradiation dose of 43 krad with 36 krad/h dose rate was applied and a subsequent characterization was performed once the Ru sensors were submitted to an 80°C annealing process during a period of 168 h. The experimental measurements have shown the stability of this sensor against total ionizing dose (TID) tests, not only in their resistance absolute values during the irradiation phase but also in the relative deviation from their values before irradiation

Coupling to breakup channels using a transformed harmonic oscillator basis

The application of a recently proposed procedure for discretizing the continuum to collision processes involving weakly bound nuclei is studied. In particular, the coupling to breakup states in the collision of d+208Pb at 50 MeV is discussed. For illustrative purposes, only the s-wave component of the bound state of the deuteron is considered, and the study is restricted to the case of nuclear s-wave breakup. The continuum discretization procedure provides a basis of transformed harmonic oscillator wave functions to accomplish the necessary calculations. Appropriate convergence of the elastic and breakup cross sections with increasing dimension of the basis is reported. In addition, it is shown that the results obtained converge to those of a standard continuum discretized coupled channels calculation, with the advantage that the convergence of the method is determined by only one parameter, namely the dimension of the basis.Ministerio de Ciencia y Tecnología PB98- 1111 FP A2000-1592-C03-02Portuguese Science and Technology Foundation SAPIENS/36282/9

Sobre la mort d'Ivan Illitx

En aquest text, els professors de l'Àrea d'Humanitats de l'Escola Universitària d'Infermeria, Fisioteràpia i Nutrició Blanquerna de la Universitat Ramon Llull, analitzen críticament una de les obres menors de Lleó Tolstoi, La mort d'Ivan Illitx. Després de contextualitzar-la, investiguen el tema central de l'obra, l'acompanyament al ben morir i fan lúcides les reflexions sobre l'art d'afrontar la mort en el nostre present
