Fraile Prieto, Luis Mario ; Mach, H. ; Paziy, V. ; Olaizola, B. ; Vedia Fernández, María Victoria ; otros, ... | American Physical Society | 2017-05-23Lifetimes of low-lying yrast states in neutron-rich Sr-94,Sr-96,Sr-98 have been measured by Germanium-gated gamma-gamma fast timing with LaBr3(Ce) detectors using the EXILL& FATIMA spectrometer at the Institut Laue-Langevin. Sr fission products [...]texto impreso
Fraile Prieto, Luis Mario ; Mach, H. ; Paziy, V. ; Olaizola, B. ; Vedia, V. | Amer Physical Soc | 2014-12-01A smooth onset of collectivity in Kr^(88,92,94,96) has been determined from reported B(E2; 2_(1)^(+) ? 0_(1)^(+)) and E(2+ 1 ) values. This is in contrast to the sudden onset in even-even Zr, Mo, and Sr isotopes. Our objective was to complete th[...]texto impreso
Fraile Prieto, Luis Mario ; Mach, H. ; Paziy, Vadym ; Vedia Fernández, María Victoria ; otros, ... | American Physical Society | 2019-07-16Lifetimes of intermediate-spin states in two rotational bands of Zr-99 have been measured. These states were populated following the neutron-induced fission of U-235 at the PF1B beamline of the Institut Laue-Langevin, Grenoble, during the EXILL-[...]texto impreso
Background: Lifetimes of nuclear excited states in fission fragments have been studied in the past following isotope separation, thus giving access mainly to the fragments' daughters and only to long-lived isomeric states in the primary fragment[...]texto impreso
Olaizola, B. ; Fraile Prieto, Luis Mario ; Mach, H. ; Cal González, J. ; Picado, E. ; Udías Moinelo, José Manuel ; otros, ... | American Physical Society | 2017-06-07The lifetime of the 0(3)(+) state in Ni-66, two neutrons below the N = 40 subshell gap, has been measured. The transition B(E2; 0(3)(+) -> 2(1)(+)) is one of the most hindered E2 transitions in the Ni isotopic chain and it implies that, unlike [...]texto impreso
Vedia, María Victoria Vedia Fernández ; Paziy, V. ; Fraile Prieto, Luis Mario ; Mach, H. | American Physical Society | 2017-09-02The existence of two close-lying nuclear states in ?³Ga has recently been experimentally determined: a 1/2? spin-parity for the ground state was measured in a laser spectroscopy experiment, while a J_? = 3/2? level was observed in transfer react[...]texto impreso
Fraile Prieto, Luis Mario ; Mach, H. ; Olaizola, B. ; Paziy, V. ; Vedia Fernández, María Victoria | Elsevier Science | 2016-09-10The gamma-ray decay of excited states of the one-valence-proton nucleus Sb-133 has been studied using cold-neutron induced fission of U-235 and Pu-241 targets, during the EXILL campaign at the ILL reactor in Grenoble. By using a highly efficient[...]
