We extend existing studies of weakly sensitive points within the framework of Tsallis non-extensive thermodynamics to include weakly insensitive points at the edge of chaos. Analyzing tangent points of the logistic map we have verified that the gener

Using exact analytical expressions of the non relativistic dipole recombination cross sections for a pure Coulomb potential summed over the quantum numbers j and l, we numerically compute the recombination cross sections in the various n states for 1

An ingot from the load of lead carried by a Roman ship sunken near Sardinia has been analysed for its composition and purity from radioactive contaminants in view of its possible use to shield low level counting experiments. Measurements carried out

We present the first quantum mechanical calculation of the electron screening effect for collisions between deuterons (d) and deuterium atoms (D) at finite collision velocity. The calculation has been performed within the framework of the adiabatic r

We study the statistical significance of a correlation between the 37 Ar counts in the Davis experiment ( Y Ar ) and the sunspot number N SS in the form Y Ar = A cos 2 ( f √ N SS ) where A and f are kept as free parameters. We discuss the significa

Stimulated by the recent debate on the physical relevance and on the predictivity of q-Gaussian formalism, we present specific analytical expressions for the parameters characterizing non-Gaussian distributions, such as the nonextensive parameter q,

We present a dynamical calculation of electron screening for d-D nuclear reactions, in the energy range relevant for star interior and fusion reactors, in the framework of the classical trajectory Monte Carlo method. It is shown that the numerical re
