Artigo IPEN-doc 24130 Control system and automation of the spectrum acquisition for a perturbed gamma-gamma angular correlation spectrometer2017 - STACHOWSKI, ADEMIR F.A.; LAPOLLI, ANDRE L.; CARBONARI, ARTUR W.; SAXENA, RAJENDRA N.This work reports results from the automation of data acquisition for a gamma-gamma perturbed angular correlation (PAC) spectrometer located in the hyperfine interactions laboratory (LIH) of IPEN. A PAC spectrometer comprises usually four scintillation detectors (BaF3 for example) and carries out time measurements from gamma rays of any two combinations of detectors in coincidence. Gamma rays come from the decay of probe nuclei embedded into the material to be studied. Measurements are generally performed as a function of temperature. The fourth-detectors PAC spectrometer was automated in Java language because it is a multiplatform and object oriented programming language, having, therefore, portability and longer lifetime due to the ease of implementation of peripherals. Finally, the software has a friendly and intuitive interface with the user being able to operate the hardware manually or automatically with time acquisitions up to 100 consecutive hours. Before each acquisition, the software sets the temperature, waits for temperature stability and records data in different files. Moreover, the software also saves in a file all information of relevant parameters during acquisition.Resumo IPEN-doc 20678 Investigation of hyperfine interactions in indiun (III) complexeing in aqueous solution2014 - LAPOLLI, ANDRE L.; CARBONARI, ARTUR W.Resumo IPEN-doc 16959 Measurements in DNA molecules using perturbed angular correlations spectroscopy2011 - SILVA, ANDREIA dos S.; AMARAL, ANTONIO A.; LAPOLLI, ANDRE L.; SAXENA, RAJENDRA N.; CARBONARI, A.W.Resumo IPEN-doc 16704 Measurements in DNA molecules using perturbed angular correlation spectroscopy2010 - SILVA, ANDREIA dos S.; AMARAL, ANTONIO A.; LAPOLLI, ANDRE L.; SAXENA, RAJENDRA N.; CARBONARI, ARTUR W.; GONCALVES, MARCOS B.Resumo IPEN-doc 18775 A six-BaFsub(2) detectors PAC spectrometer for measurements with short lived nuclear probes2012 - DOMIENIKAN, CLAUDIO; LAPOLLI, ANDRE L.; SANTOS, BRIANNA B. dos; CARBONARI, ARTUR W.; SAXENA, RAJENDRA N.; SCHOUERI, ROBERTO M.Resumo IPEN-doc 18782 Investigation of hyperfine interactions in DNA nitrogenous bases using perturbed angular correlation spectroscopy2012 - SILVA, ANDREIA dos S.; CARBONARI, ARTUR W.; LAPOLLI, ANDRE L.Artigo IPEN-doc 19260 Investigation of hyperfine interactions in DNA nitrogenous bases using perturbed angular correlation spectroscopy2013 - SILVA, ANDREIA dos S.; CARBONARI, ARTUR W.; LAPOLLI, ANDRE L.; SAXENA, RAJENDRA N.; SAITOVITCH, HENRIQUEArtigo IPEN-doc 16856 Investigation of hyperfine interactions in hafnioum compounds with Fsup(1-), OHsup(1-), and EDTA ligants by perturbed 'gamma-gamma' angular correlation2011 - AMARAL, ANTONIO A.; SILVA, ANDREIA dos S.; LAPOLLI, ANDRE L.; CARBONARI, ARTUR W.; SAXENA, RAJENDRA N.Artigo IPEN-doc 17065 Electronic module for 6-BaFsub(2) - detectors positioning control2011 - DOMIENIKAN, CLAUDIO; LAPOLLI, ANDRE L.; TOLEDO, FABIO de; ZANINI, AMELIA Y.K.; TRINDADE, GIVANILSON da S.Artigo IPEN-doc 20105 Cd hyperfine interactions in DNA bases and DNA of mouse strains infected withy Trypanosoma cruzi investigated by perturbed angular correlation spectroscopy and ab initio calculations2014 - PETERSEN, PHILIPPE A.D.; SILVA, ANDREIA S.; GONCALVES, MARCOS B.; LAPOLLI, ANDRE L.; FERREIRA, ANA M.C.; CARBONARI, ARTUR W.; PETRILLI, HELENA M.
