New isomeric states in the neutron-rich nuclei near $Z\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}28$ and $N\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}40$ shell closures have been identified among reaction products of a $60.3A$ MeV ${}^{86}\mathrm{Kr}$ beam on ${}^{\mathrm{nat}}\mathrm{Ni}$ target. From measured decay properties information about excited their nuclear structure has obtained. The isomerism is related mostly to occupation neutron ${g}_{9/2}$ orbital, an intruder...
To investigate the behavior of N = 14 neutron gap far from stability with a neutron-sensitive probe, proton elastic and 2(1)+ inelastic scattering angular distributions for neutron-rich nucleus 22O were measured using MUr à STrip detector array at Grand Accélérateur National d'Ions Lourds facility. A deformation parameter beta(p,p') 0.26 +/- 0.04 is obtained state, much lower than in 20O, showing weak contribution to this state. microscopic analysis was performed matter transition densities...
In an experiment at the SISSI/LISE facility of GANIL, we used projectile fragmentation a ${}^{78}\mathrm{Kr}$ primary beam 73 MeV/nucleon to produce new isotopes astrophysical interest. We obtained clear evidence for existence five ${}^{60}\mathrm{Ga}$, ${}^{64}\mathrm{As}$, ${}^{69,70}\mathrm{Kr}$, and ${}^{74}\mathrm{Sr}$. However, did not find any ${}^{69}\mathrm{Br}$, whereas comparable nuclei were observed with more than 1000 counts. The isotope ${}^{69}\mathrm{Br}$ is thus deduced be...
A decay spectroscopic study of the neutron-rich isotopes has been performed using fragmentation a $^{86}\mathrm{Kr}$ primary beam. Fragments from this reaction have selected by LISE2000 spectrometer at Grand Acc\'el\'erateur National d'Ions Lourds (GANIL). Half-lives 29 isotopes, including first ones identified for $^{61}\mathrm{Ti}$ ($15\ifmmode\pm\else\textpm\fi{}4$ ms), $^{64}\mathrm{V}$ ($19\ifmmode\pm\else\textpm\fi{}8$ and $^{71}\mathrm{Fe}$ ($28\ifmmode\pm\else\textpm\fi{}5$...
The yrast ${J}^{\ensuremath{\pi}}={8}^{+}$ states in neutron-rich $^{70,72,74,76}\mathrm{Ni}$ nuclei are predicted to be isomeric. present paper describes two GANIL experiments. In the first of them a search was made for ${8}^{+}$ isomeric $^{72,74}\mathrm{Ni}$ via fragmentation $^{76}\mathrm{Ge}$ using ion $\ensuremath{\gamma}$-decay correlation technique. Although these were not observed, limits their lifetimes determined. second experiment decay spectroscopy $^{70,72}\mathrm{Co}$...
The single-event effects response of three different III-V field-effect transistor technologies (GaAs MESFET, InAlAs/InGaAs HEMT, and AlSb/InAs HEMT) is measured for MeV GeV heavy-ion irradiation. These measurements reveal significant charge enhancement very slow, microsecond-timescale relaxation times the GaAs devices, with a much faster recovery from ionizing event observed HEMTs.
The structure of nuclei far from stability can be investigated by means in-beam gamma spectroscopy using both stable and radioactive beams. Two such experiments have been recently performed at GANIL. i) Secondary beams neutron-rich Ge, Zn Ni isotopes around N=40 were produced the fragmentation a primary 86 Kr beam, analyzed LISE3 spectrometer. For transitions between 0+ ground state first 2+ state, B(E2) values extracted Coulomb excitation cross-section measurement. Some obtained results...
The Energy-Loss Function (ELF) of silicon has been used to calculate differential and total inelastic cross-sections incident electrons. model validated in the 16.7 eV-50 keV energy range by comparing stopping powers, mean free paths ranges experimental evaluated ICRU data. cross sections were then simulate low-energy electron tracks using Geant4-DNA toolkit. Generation electrons are clearly seen. obtained consistent with
Ion stopping experiments in plasma for beam energies of few hundred keV per nucleon are great interest to benchmark the stopping-power models context inertial confinement fusion and high-energy-density physics research. For this purpose, a specific ion detector on chemical-vapor-deposition diamond basis has been developed precise time-of-flight measurements energy loss. The electrode structure is interdigitated maximizing its sensitivity low-energy ions, it finger width 100 μm spacing 500...
