### [hal-01582779] Search for neutrinoless quadruple-$\beta$ decay of $^{150}$Nd with the NEMO-3 detector

7 septembre 2017

We report the results of a first experimental search for lepton number violation by four units in the neutrinoless quadruple-β decay of Nd150 using a total exposure of 0.19 kg yr recorded with the NEMO-3 detector at the Modane Underground Laboratory. We find no evidence of this decay and set (...)

### [hal-01554897] A novel segmented-scintillator antineutrino detector

5 juillet 2017

The next generation of very-short-baseline reactor experiments will require compact detectors operating at surface level and close to a nuclear reactor. This paper presents a new detector concept based on a composite solid scintillator technology. The detector target uses cubes of (...)

20 juin 2016

The NEMO-3 experiment at the Modane Underground Laboratory has investigated the double-$\beta$ decay of $^48\rm Ca$. Using $5.25$ yr of data recorded with a $6.99\,\rm g$ sample of $^48\rm Ca$, approximately $150$ double-$\beta$ decay candidate events have been selected with a (...)

9 novembre 2015

The NEMO-3 detector, which had been operating in the Modane Underground Laboratory from 2003 to 2010, was designed to search for neutrinoless double $\beta$ ($0\nu\beta\beta$) decay. We report final results of a search for $0\nu\beta\beta$ decays with $6.914$ kg of $^100$Mo using the entire (...)

### [in2p3-00912877] Search for Neutrinoless Double-Beta Decay of $^{100}$Mo with the NEMO-3 Detector

2 décembre 2013

We report the results of a search for the neutrinoless double-$\beta$ decay (0$\nu\beta\beta$) of $^100$Mo, using the NEMO-3 detector to reconstruct the full topology of the final state events. With an exposure of 34.7 kg.y, no evidence for the 0$\nu\beta\beta$ signal has been found, yielding a (...)

### Measurement of the 6Li charge state distributions following the 6He+ beta decay

19 novembre 2012

We measure the probability of "shake-off" ionization of the daughter nucleus in the β decay of 6He+ ions confined in a transparent Paul trap. This measurement, in good agreement with theoretical calculations, allows to reduce systematic error contributions in previous β-v correlation experiments (...)
