Fraile Prieto, Luis Mario ; Benito García, Jaime ; Carmona, M. ; Martínez Pérez, María Cristina ; Sánchez-Tembleque Verbo, Victor ; Udías Moinelo, José Manuel ; Vedia Fernández, María Victoria ; Villa Abaunza, Amaia ; otros, ... | American Physical Society | 2019-02-05Excited states in Sn-133 were investigated through the beta decay of In-133 at the ISOLDE facility. The ISOLDE Resonance Ionization Laser Ion Source (RILIS) provided isomer-selective ionization for In-133, allowing us to study separately, and in[...]texto impreso
Fraile Prieto, Luis Mario ; Vedia Fernández, María Victoria ; otros, ... | Elsevier Science BV | 2018-12-01DTAS is a segmented total absorption y-ray spectrometer developed for the DESPEC experiment at FAIR. It is composed of up to eighteen NaI(Tl) crystals. In this work we study the performance of this detector with laboratory sources and also under[...]texto impreso
Fraile Prieto, Luis Mario ; Vedia Fernández, María Victoria ; otros, ... | Amer Physical Soc | 2020-08-18Decay spectroscopy of the long-lived states in Tl-186 has been performed at the ISOLDE Decay Station at ISOLDE, CERN. The a decay from the low-spin (2(-)) state in Tl-186 was observed for the first time and a half-life of 3.4(-0.)(4)(+0.5) s was[...]texto impreso
Benito García, Jaime ; Fraile Prieto, Luis Mario ; Carmona, M. ; Galve Lahoz, Pablo ; García Díez, Miguel ; Ibañez, P. ; López Montes, Alejandro ; Martínez, M. C. ; Sánchez Parcerisa, Daniel ; Sánchez Tembleque, Víctor ; Udías Moinelo, José Manuel ; Vedia Fernández, María Victoria ; Villa Abaunza, Amaia ; otros, ... | Amer Physical Soc | 2020-07-29The structure of the doubly magic Sn-132(50)82 has been investigated at the ISOLDE facility at CERN, populated both by the beta(-) decay of In-132 and beta(-)-delayed neutron emission of In-133. The level scheme of Sn-13(2) is greatly expanded w[...]texto impreso
Fraile Prieto, Luis Mario ; Vedia Fernández, María Victoria ; otros, ... | American Physical Society | 2017-07-27The beta decay of Tc-100 has been studied by using the total absorption gamma-ray spectroscopy technique at the Ion Guide Isotope Separator On-Line facility in Jyvaskyla. In this work the new Decay Total Absorption gamma-ray Spectrometer in coin[...]texto impreso
Nuclei with few valence particles outside of a doubly-magic core provide valuable information about single-particle energies, nucleon-nucleon e_ective interactions and may give insight into the onset of collectivity. The region around 132Sn draw[...]texto impreso
Fraile Prieto, Luis Mario ; Carmona Gallardo, Mariano ; Vedia Fernández, María Victoria | Jagellonian University | 2017-03A fast-timing experiment was performed at the Argonne National Laboratory in December 2015 and January 2016, measuring decay radiation of fission products from a Cf-252 fission source. Details of the set-up, integration with Digital Gammasphere,[...]texto impreso
In order to investigate the evolution of nuclear deformation in the region of the chart of nuclides around mass numbers A similar or equal to 110 and A similar or equal to 150, an experiment was performed at the Argonne National Laboratory where[...]texto impreso
Fraile Prieto, Luis Mario ; Vedia Fernández, María Victoria ; Ibáñez García, Paula Beatriz ; Paziy, Vadym ; Pérez Liva, Mailyn ; Picado, E. ; Vidal, M. | Amer Physical Soc | 2016-04-04The levels in Sn-129 populated from the beta(-) decay of In-129 isomers were investigated at the ISOLDE facility of CERN using the newly commissioned ISOLDE Decay Station (IDS). The lowest 1/2(+) state and the 3/2(+) ground state in 129Sn are ex[...]texto impreso
Fraile Prieto, Luis Mario ; Gallardo, M. C. ; Vedia Fernández, María Victoria ; otros, ... | Amer Physical Soc | 2018-10-03The C-12(alpha,gamma)O-16 reaction plays a central role in astrophysics, but its cross section at energies relevant for astrophysical applications is only poorly constrained by laboratory data. The reduced a width, gamma(11), of the bound 1(-) l[...]texto impreso
Benito García, Jaime ; Fraile Prieto, Luis Mario ; Sánchez-Tembleque Verbo, Victor ; Vedia Fernández, María Victoria ; otros, ... | American Physical Society | 2020-02-26We report on the measurement of lifetimes of excited states in the near-mid-shell nuclei Dy-164,Dy-166 using the gamma-ray coincidence fast-timing method. The nuclei of interest were populated using reactions between an O-18 beam and a gold-back[...]texto impreso

Isomer selective ionization using the ISOLDE RILIS enabled the beta decays of In-133(gs) (I-pi = 9/2(+)) and In-133m (I-pi = 1/2(-)) to be studied indep[...]texto impreso
Fraile Prieto, Luis Mario ; Vedia Fernández, María Victoria ; otros, ... | Elsevier Science BV | 2019-06-10Gamow-Teller beta decay is forbidden if the number of nodes in the radial wave functions of the initial and final states is different. This Delta n = 0 requirement plays a major role in the beta decay of heavy neutron-rich nuclei, affecting the [...]
