R.; PELLEGRI, L.© 2022 Institute of Physics Publishing. All rights reserved.The use of double charge exchange reactions is discussed in view of their application to extract information that may be helpful to determinate the nuclear matrix elements entering in the expression of neutrinoless double beta decay half-life. The strategy adopted in the experimental campaigns performed at INFN - Laboratori Nazionali del Sud and in the analysis methods within the NUMEN project is briefly described, emphasizing the advantages of the multi-channel approach to nuclear reaction data analysis. An overview on the research and development activities on the MAGNEX magnetic spectrometer is also given, with a focus on the chosen technological solutions for the focal plane detector which will guarantee the performances at high-rate conditions.
- Isomeric state in the odd-odd 68Ga nucleus(2022-01-05) ESCUDEIRO, R.; VASCONCELOS, C. E. C; ALLEGRO, P. R. P.; MEDINA, N. H.; TUFEN, D. L.; ADDED, N.; AGUIAR, V. A. P.; ALBERTON. S. G. P. N.; ALCANTARA-NUNEZ, J.; Marcilei Aparecida Guazzelli; MACCHIONE. E. L. A.; OLIVEIRA, J. R. B.; RIBAS, R. V.; SCARDUELLI, V. B.© 2022 Institute of Physics Publishing. All rights reserved.The half life of the 7− isomeric state of the odd-odd 68Ga nucleus was measured using a particle-γ delayed coincidence technique. The 68Ga nuclei were produced using the fusion-evaporation reaction 55Mn(16O, 2pn)68Ga at 55 MeV incident beam energy. The beam was produced by the 8 MV Pelletron accelerator of the Nuclear Physics Open Laboratory of the University of São Paulo. The half life was measured using the Isomeric State Measurement System (SISMEI). The obtained value was 60.83(25) ns, compatible with previous measurements. The 68Ga excited states were well described with the Large Scale Shell Model using the JUN45 residual interaction.
