Multinucleon transfer reactions were employed in a series of experiments at Legnaro National Laboratories INFN and the Tandem Laboratory Horia Hulubei Institute Bucharest. The main aim was to investigate shape coexistence phenomenon even–even Sn isotopes, with mass \(A=112\)–118, through lifetime measurements excited \(0^+\) states. Recent Monte Carlo Shell Model (MCSM) calculations predict, fact, appearance well-separated secondary minima potential energy surfaces these corresponding...
A novel technique, the so-called ‘reversed plunger’, was used for first time to measure lifetimes of nuclear excited states on order picoseconds in heavy neutron-rich nuclei at Legnaro National Laboratories. Preliminary spectra show that commissioning technique successfully performed employing Advanced Gamma-Ray Tracking Array (AGATA), magnetic spectrometer PRISMA, and plunger device reversed configuration.
This work describes the new facility for applied nuclear physics at University of Sao Paulo, mainly irradiation electronic devices. It is a setup composed quadrupole doublet beam focusing/defocusing plus multiple scattering through gold foils to produce low intensity, large-area, and high-uniformity heavy-ion beams from 1H 107Ag. Beam intensities can be easily adjusted 102 particles cm2/s hundreds nA an area as large 2.0 cm2 uniformity better than 90%. Its chamber has high-precision...
Two new gamma spectrometer projects are under development, both with some challenging technical characteristics in common, one for the investigation of weakly bound nuclear beam reactions at near barrier energies, and other measurement double charge exchange 15-70 MeV per nucleon range. The first is being developed tested IFUSP, going to be built installed LNS, INFN, NUMEN collaboration. main two presented discussed.
This study presents an alternative method to determine isotope ratios using a medium energy accelerator and simultaneously measuring the charged particles gamma-rays produced in nuclear reaction.
Abstract The half life of the 7 − isomeric state odd-odd 68 Ga nucleus was measured using a particle-γ delayed coincidence technique. nuclei were produced fusion-evaporation reaction 55 Mn( 16 O,2pn) at MeV incident beam energy. by 8 MV Pelletron accelerator Nuclear Physics Open Laboratory University São Paulo. Isomeric State Measurement System (SISMEI). obtained value 60.83(25) ns, compatible with previous measurements. excited states well described Large Scale Shell Model JUN45 residual...
