      The goal of this study is to provide a benchmark for the use of Monte Carlo simulation when applied to coincidence summing corrections. The examples are based on simple geometries: two types of germanium detectors and four ...

    • Constraining the 30P(p,¿¿)31S Reaction Rate in ONe Novae via the Weak, Low-Energy, ß-Delayed Proton Decay of 31Cl 

      Budner, Tamas; Friedman, Matt; Wrede, Christopher; Brown, B. Alex; José Pont, Jordi; Perez Loureiro, David; Sun, Lijie; Surbrook, Jason; Ayyad, Yassid; Bardayan, D. W.; Chae, Kyungyuk; Chen, Alan A.; Chipps, Kelly A.; Cortesi, Marco; Glassman, Brent; Hall, Matthew R.; Janasik, Mark; Liang, Jing; O'Malley, Patrick; Pollacco, E.; Psaltis, Athanasios; Stomps, Jordan; Wheeler, Tyler (American Institute of Physics (AIP), 2022-05-06)
      Article
      Open Access
      The 30P(p,¿)31S reaction plays an important role in understanding the nucleosynthesis of A=30 nuclides in oxygen-neon novae. The Gaseous Detector with Germanium Tagging was used to measure 31Cl ß-delayed proton decay through ...

    • Determining the probability of locating peaks using computerized peak-location methods in gamma-ray spectra as a function of the relative peak-area uncertainty 

      Ali Santoro, María Del Carmen; Boshkova, Tatiana; Anagnostakis, Mario J.; Camacho García, Antonia; Fornaciari Iljadica, Marra C.; Collins, Sean M.; Ubiratan Delgado, José (2020-01-01)
      Article
      Open Access
      The probabilities of locating peaks with a high relative peak-area uncertainty were determined empirically with nine types of peak-location software used in laboratories engaged in gamma-ray spectrometry measurements. It ...

      La determinació de l’activitat gamma en mostres radioactives per part dels detectors HPGe es realitza a partir de les corbes d’eficiència en energia, determinades prèviament a partir de fonts patró. Aquest patrons, que ...

    • Measurement of the prompt fission y -rays from slow neutron-induced fission of 235 U with STEFF 

      Wright, Tobias; Smith, Alastair; Sosnin, Nikolay Viktorovich; Bennett, Sam; Davies, Paul John; Popescu, Alexandra; Ryan, Joanne; Sekhar, Adhitya; Warren, Saskia; Aberle, Oliver; Amaducci, Simone; Andrzejewski, Józef; Calviño Tavares, Francisco; Casanovas Hoste, Adrià; Cortés Rossell, Guillem Pere; Tarifeño Saldivia, Ariel Esteban (Springer, 2024-03-19)
      Article
      Open Access
      The average energy and multiplicity of prompt y -rays from slow neutron-induced fission of 235 U have been measured using the STEFF spectrometer at the neutron time-of-flight facility n_TOF. The individual responses from ...

    • Systematic influences on the areas of peaks in gamma-ray spectra that have a large statistical uncertainty 

      Bruggeman, M.; Collins, S. M.; Done, Laurentiu; Duch Guillen, María Amor; Serrano Carreño, M. Isabel (2018-04-01)
      Article
      Open Access
      A method is presented for calculating the expected number of counts in peaks that have a large relative peak-area uncertainty and appear in measured gamma-ray spectra. The method was applied to calculations of the correction ...
