Search for nuclearites with the SLIM detector

The strange quark matter (SQM) may be the ground state of QCD; nuggets of SQM could be present in cosmic rays (CR). SLIM is a large area experiment, using CR39 and Makrofol track etch detectors, presently depl...

Calibration with relativistic and low-velocity ions of a CR39 nuclear track detector

We present experimental results on the calibration of the CR39 nuclear track detector, manufactured by the Intercast Europe Co., of Parma (Italy). The calibration was performed with several ions of different k...

Solar variability and ring widths in fossil trees

We have analysed ring width sequences of 1.3 My old fossil trees, grown with no water deficit, in Dunarobba forest (Italy). We find evidence for a modulation period of the annual ring growth widths on time sca...

400 Year record of Δ¹⁴C in tree rings: The solar-activity cycle before, during and after maunder minimum and the longer cyclesin tree rings: The solar-activity cycle before, during and after maunder minimum and the longer cycles

The analysis of Δ¹⁴C in dated tree ring series from 1600 to 1940 AD is presented. The data series is divided into two parts, namely before and after 1780 AD to better study the characteristic of its cyclicities b...

The subharmonics of the 22-year solar cycle

We briefly discuss the existence in various aspects of solar activity of the precise periodicities of Hale cycle (22y), Gleissberg cycle (88y) and of 132y recently discovered by our group. We consider also the...

The power spectrum of cosmic rays. The low-frequency range (1·10⁻¹¹÷1·10⁻⁵) Hz

The cosmic-ray power spectral density in the frequency band (5·10⁻⁸÷1·10⁻⁵) Hz has been estimated from data of mid- and high-latitude neutron monitors and low latitude ion chamber data. The power spectral density...

Time series variation analysis with Fourier vector amplitudes

A method is presented here to detect hidden trains of recurrences or periodicities in a time series ofN equispaced data. The complex amplitudes of the harmonic components of period τ of subseries of lengthT are c...

The power spectrum analysis of the cosmic-ray diurnal variation

We present a study of the CR diurnal variation by means of the power spectrum analysis of the neutron monitor flux as observed by a group of nonpolar stations. The power spectrum structure indicates a differen...
