Abstract

At the underground laboratory of Monte dei Cappuccini (OATo-INAF) in Torino (Italy) we set up selective HPGe-NaI(Tl) spectrometers for measurements of cosmogenic radioisotopes in meteorites in order to study centennial-scale modulation of solar activity. ⁴⁴ Ti is a suitable proxy for this timescale, but its detection is difficult due to the strong interference by naturally occurring ²¹⁴ Bi. In order to optimize the extraction of the ⁴⁴ Ti signal, we have developed software procedures specifically designed to improve selectivity of the Ge-NaI detectors coincidence.
