Further investigation of the initial fission-track length and geometry factor in apatite fission-track thermochronology
(2013-08-01)
The external detector method (EDM) is a widely used technique in fission track thermochronology (FTT) in which two different minerals are concomitantly employed: spontaneous tracks are observed in apatite and induced ones ...
ζ1 + ζ2 Reticuli binary system: a puzzling chromospheric activity pattern
(Wiley Blackwell Publishing, Inc, 2018-05)
We perform, for the first time, a detailed long-term activity study of the binary system ζ Ret. We use all available HARPS spectra obtained between the years 2003 and 2016. We build a time series of the Mount Wilson S index ...

A comparison between neutron-fluence measurements using metal-activation monitors and standard glasses calibrated via thin uranium-fission monitors and via ηq method
(2013-04-02)
The two fundamental approaches to fission-track dating involve either an explicit determination of the thermal neutron fluence (φ-method) or a calibration against age standards (ζ-method). The neutron fluence measurements ...

Dependence of the broad frequency dielectric spectra of colloidal polystyrene particle suspensions on the difference between the counterion and co-ion diffusion coefficients
(Academic Press Inc Elsevier Science, 2006-12)
Dielectric properties of four suspensions of spherical polystyrene particles were measured at 25 ◦ C over a broad frequency range extending from 100 Hz to 10 MHz, using a HP 4192 A Impedance Analyzer. The instrument was ...
