The present paper proposes an algorithm to improve the energy resolution of two-step cascade spectrum. The energy resolution plays an important role in the domain of gamma spectrum analysis. The better the energy resolution is, the better the ability of peak resolving is. The algorithm is constructed based on an analyze of energy resolution of the summation amplitude of coincident pulses spectrometer using the analogue technique. The algorithm proposed has been tested on some two-step cascade spectra of 164Dy nucleus obtained from the (n, ) reaction experiment using the gamma – gamma coincidence spectrometer at Dalat Nuclear Research Institute. Two-step cascade spectra corresponding to the cascade decays from the compound state to final states whose energies are 0, 74, and 242 keV have been evaluated. The results obtained show that the energy resolution of the two-step cascade spectrum has been reduced by 1.05 to 2.04 times within the energy range of 586 to 6830 keV. Our algorithm can therefore be applied to improve the ability of peak deconvolution, the accuracy, and the realibility in analyzing two-step cascade spectra.

LABURPENA: Estatu konposatuetan beharrezkotzat jotzen dute zehaztea zer eragin daukan deszentralizazio politikoak lurraldeko hizkuntz eskubideen aintzatespenean, eskubide horietan nolabaiteko aniztasuna finkatuta, eta noiz den aniztasun hori berdintasun-eskakizunaren aurkakoa, estatu konposatu guztien oinarrian baitago. Era horretako estatuetan, eskumenak banatzeko sistemek bide desberdinak erabiltzen dituzte oreka zail horri ekitean; bide horietako bat da estatuari eskumena ematea eskubideetako batzuk estatuaren lurralde osoan era homogeneoan arautzeko, eta, horrela, autonomia politikotik eratortzen den aniztasuna eremu homogeneo horretatik kanpo bakarrik izan daiteke, eta inola ere ez eremu horren barruan. Teknika horren adibide argia daukagu Espainian 149.1.1 CE artikuluan, eta adibiderik berriena Italiako Konstituzioaren 117.II.m) artikuluan dago, hain zuzen ere, lan honetan aztertuko dena. RESUMEN: En los Estados compuestos se plantea la necesidad de determinar hasta qué punto la descentralización política puede influir en el reconocimiento de derechos a lo largo del territorio, determinando un cierto elemento de variedad en el contenido de estos, y cuándo tal variedad resultaría contraria a la exigencia de igualdad que debe hallarse también en la base de todo Estado compuesto. Los sistemas de distribución competencial en estos Estados abordan este complejo equilibrio mediante diferentes técnicas, una de las cuales consiste en otorgar al Estado una competencia para regular una parte de los derechos con carácter homogéneo en todo el territorio estatal, de modo que la variedad derivada de la autonomía política solo sea posible más allá de esa zona homogénea, pero no dentro de ella. De esta técnica, de la que en España tenemos un ejemplo evidente en el art. 149.1.1 CE, el exponente más reciente en el tiempo es el art. 117.II.m) de la Constitución italiana, que es el objeto de análisis de este trabajo. ABSTRACT: In the compound States it’s necessary to set to what extent political decentralization may influence the recognition of rights over the territory, determining a CErtain element of variety in the content of these, and when such a variety would be contrary to the requirement of equality, that must also be on the basis of all compound State. The systems of distribution of competences in these States address this complex balance using different techniques, one of which is to give the State a power to regulate in an uniform way a part of the rights, so the variety derived from political autonomy will be possible only beyond that homogeneous area but not within it. In Spain we have a clear example of this technique in art. 149.1.1 CE, and the latest exponent in time of this way is art. 117. II.m) of the Italian Constitution, which is the object of analysis of this work.

Abstract The TOTEM experiment at the LHC has performed the first measurement at $$\sqrt{s} = 13\,\mathrm{TeV}$$s=13TeV of the $$\rho $$ρ parameter, the real to imaginary ratio of the nuclear elastic scattering amplitude at $$t=0$$t=0, obtaining the following results: $$\rho = 0.09 \pm 0.01$$ρ=0.09±0.01 and $$\rho = 0.10 \pm 0.01$$ρ=0.10±0.01, depending on different physics assumptions and mathematical modelling. The unprecedented precision of the $$\rho $$ρ measurement, combined with the TOTEM total cross-section measurements in an energy range larger than $$10\,\mathrm{TeV}$$10TeV (from 2.76 to $$13\,\mathrm{TeV}$$13TeV), has implied the exclusion of all the models classified and published by COMPETE. The $$\rho $$ρ results obtained by TOTEM are compatible with the predictions, from other theoretical models both in the Regge-like framework and in the QCD framework, of a crossing-odd colourless 3-gluon compound state exchange in the t-channel of the proton–proton elastic scattering. On the contrary, if shown that the crossing-odd 3-gluon compound state t-channel exchange is not of importance for the description of elastic scattering, the $$\rho $$ρ value determined by TOTEM would represent a first evidence of a slowing down of the total cross-section growth at higher energies. The very low-|t| reach allowed also to determine the absolute normalisation using the Coulomb amplitude for the first time at the LHC and obtain a new total proton–proton cross-section measurement $$\sigma _{\mathrm{tot}} = (110.3 \pm 3.5)\,\mathrm{mb}$$σtot=(110.3±3.5)mb, completely independent from the previous TOTEM determination. Combining the two TOTEM results yields $$\sigma _{\mathrm{tot}} = (110.5 \pm 2.4)\,\mathrm{mb}$$σtot=(110.5±2.4)mb.
