dc.description.abstract	The most precise measurements to date of the 3ΛH lifetime τ and Λ separation energy BΛ are obtained using the data sample of Pb-Pb collisions at √sNN=5.02 TeV collected by ALICE at the LHC. The 3ΛH is reconstructed via its charged two-body mesonic decay channel (3ΛH→3He+π− and the charge-conjugate process). The measured values τ=[253±11(stat)±6(syst)] ps and BΛ=[102±63(stat)±67(syst)] keV are compatible with predictions from effective field theories and confirm that the 3ΛH structure is consistent with a weakly bound system.	en

Precision mass measurements beyond ^{132}Sn: Anomalous behaviour of odd-even staggering of binding energies

Hakala, Jani; Dobaczewski, Jacek; Gorelov, Dmitry; Eronen, Tommi; Jokinen, Ari; Kankainen, Anu; Kolhinen, Veli; Kortelainen, Markus; Moore, Iain; Penttilä, Heikki; Rinta-Antila, Sami; Rissanen, Juho; Saastamoinen, Antti; Sonnenschein, Volker; Äystö, Juha (American Physical Society, 2012)

Atomic masses of the neutron-rich isotopes 121–128Cd, 129;131In, 130–135Sn, 131–136Sb, and 132–140Te have been measured with high precision (10 ppb) using the Penning-trap mass spectrometer JYFLTRAP. Among these, the ...
Effective axial-vector strength within proton-neutron deformed quasiparticle random-phase approximation

Delion, D. S.; Dumitrescu, A.; Suhonen, J. (American Physical Society, 2019)

We use the available experimental Gamow-Teller β− and β+/EC (electron-capture) decay rates between 0+ and 1+ ground states in neighboring even-even and odd-odd nuclei, combined with 2νββ half-lives, to analyze the influence ...

(Elsevier BV, 2020)

A charge plunger device has been commissioned based on the DPUNS plunger (Taylor et al., 2013) using the in-flight mass separator MARA at the University of Jyväskylä. The 152Sm(32S,4n)180Pt reaction was used to populate ...
