In this work we survey the detectability of the β− channel of 50
23V leading to the first excited 2+ state in 50
24Cr.
The electron-capture (EC) half-life corresponding to the transition of 50
23V to the first excited 2+ state in 50
22Ti
had been measured earlier. Both of the mentioned transitions are 4th-forbidden non-unique. We have performed
calculations of all the involved wave functions by using the nuclear shell model with the GXPF1A interaction
in the full f-p shell. The computed half-life of the EC branch is in good agreement with the measured one. The
predicted half-life for the β− branch is in the range ≈2 × 1019 yr whereas the present experimental lower limit
is 1.5 × 1018 yr. We discuss also the experimental lay-out needed to detect the β−-branch decay.

M.; Van Duppen, P.; Vedia, V.; Villa, A.; Viñals, S.; Wadsworth, R.; Walters, W. B.; Warr, N.; Wilkins, S. G. (American Physical Society (APS), 2021)The β decay of the neutron-rich 134In and 135In was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number Z = 50 above the N = 82 shell. The ... -
Phase-space factors and half-life predictions for Majoron-emitting β−β− decay
Kotila, Jenni-Mari; Barea, J.; Iachello, F. (American Physical Society, 2015)A complete calculation of phase space factors (PSFs) for Majoron-emitting 0νβ − β − decay modes is presented. The calculation makes use of exact Dirac wave functions with finite nuclear size and electron screening and ... -

Defranchi Bisso, Federica (2016)My Master Thesis is titled “Determination of the fission half-life for the isotope 250No”. The data I analyse in this work were collected in an experiment run in April, 2015, at the accelerator laboratory of the ... -
Measurement of the double-beta decay half-life and search for the neutrinoless double-beta decay of Ca48 with the NEMO-3 detector
NEMO-3 Collaboration (American Physical Society, 2016)The NEMO-3 experiment at the Modane Underground Laboratory investigates the double-beta decay of Ca48. Using 5.25 yr of data recorded with a 6.99 g sample of Ca48, approximately 150 double-beta decay candidate events are ... -
Measurement of the 2νββ decay half-life and search for the 0νββ decay of 116Cd with the NEMO-3 detector
NEMO-3 Collaboration (American Physical Society, 2017)The NEMO-3 experiment measured the half-life of the 2νββ decay and searched for the 0νββ decay of 116Cd. Using 410 g of 116Cd installed in the detector with an exposure of 5.26 y, (4968±74) events corresponding to the 2νββ ...
