Double-beta decays of 100Mo from the 6.0195-year exposure of a 6.914 kg high-purity sample were recorded by the NEMO-3 experiment that searched for neutrinoless double-beta decays. These ultrarare transitions to 100Ru have a half-life of approximately 7×1018 years and have been used to conduct the first-ever search for periodic variations of this decay mode. The Lomb-Scargle periodogram technique, and its error-weighted extension, were employed to look for periodic modulations of the half-life. Data show no evidence at the 95% confidence level of modulations with amplitude greater than 2.5% in the frequency range of 0.33225yr−1 to 360yr−1.

Kaksoisbeetahajoaminen : neutriinon massa ja sen kokeellinen määrittäminen

Misitano, Giovanni (2016)

Työssä tutustutaan kaksoisbeetahajoamiseen ilmiönä, ja erityisesti neutriinotonta kaksoisbeetahajoamista etsiviin kokeisiin. Lyhyen ilmiön historiaan keskittyvän johdannon jälkeen käsitellään kokeiden kannalta oleellinen ...
Detailed spectroscopy of the neutron-deficient bismuth isotopes ¹⁹³,¹⁹⁵Bi

Herzáň, Andrej (University of Jyväskylä, 2015)

Two experiments aiming to study the shape coexistence and competing structures in 193Bi and 195Bi isotopes have been performed at the Accelerator laboratory of the University of Jyv askyl a, Finland (JYFL). Many new ...
