Shell-model studies relevant for the low-energy Coulomb excitation in Zn isotopes
Springer Science and Business Media LLC - Tập 59 - Trang 1-13 - 2023
I. Ahmed, R. Kumar, K. Hadyńska-Klȩk, C. Qi
The low-lying nuclear structure of even-even Zn isotopes ranging from $$^{62}$$ Zn to $$^{70}$$ Zn has been comprehensively examined through large scale shell model calculations. These calculations encompassed the f $$_{5/2}\textrm{p}_{3/2,1/2}\textrm{g}_{9/2}$$ (fpg) model space without any truncation, employing $$^{56}$$ Ni as an inert core. Two different effective interactions, JUN45 and jj44b,... hiện toàn bộ

The low-energy structures of the radioactive nuclei 20, 21Na have been examined using Coulomb excitation at the TRIUMF-ISAC radioactive ion beam facility. Beams of ∼ 5×106 ions/s were accelerated to 1.7MeV/A and Coulomb excited in a 0.5mg/cm^2 natTi target. Two TIGRESS HPGe clover detectors perpendicular to the beam axis were used for $ \gamma$ -ray detection, while scattered nuclei were observed ... hiện toàn bộ

Neutron pick-up in the 55Mn(d, t)54Mn reaction
Springer Science and Business Media LLC - Tập 54 - Trang 1-10 - 2018
E. N. Cardozo, M. J. Ermamatov, J. L. Ferreira, B. Paes, M. Sinha, J. Lubian
In this paper, we analyze the one-neutron pick-up from the 55Mn target when it is bombarded by 17MeV deuteron, by performing coupled reaction channel (CRC) calculations. Spectroscopic amplitudes for CRC calculations, and structural information such as reduced B(E2) transition probabilities, quadrupole, and magnetic momenta, are obtained from shell-model calculations using the fp-kb3 interaction.

AGATA: mechanics and infrastructures

Morrall, L. Ramina, M. Rampazzo, A. Roger, J. Simpson, N. Solenne, O. Stézowski, S. Tzvetkov, L. Zago, M. Zielińska
The successful operation of AGATA requires a complex mechanical support structure for the safe and reliable operation of the detectors. Three mechanical structures were designed for the scientific campaigns at LNL, GSI and GANIL, each accommodating an increasing number of detectors. The present phase of the project, to increase the number of detectors from 60 to 180 (the $$4\pi $$ spectrometer), r... hiện toàn bộ

We report on baryon resonance production and decay in proton-proton collisions at a kinetic energy of 3.5 GeV based on data measured with HADES. The exclusive channels $ pp \rightarrow np\pi^{+}$ and $ pp\rightarrow pp\pi^{0}$ as well as $ pp\rightarrow ppe^{+}e^{-}$ are studied simultaneously for the first time. The invariant masses and angular distributions of the pion-nucleon systems were studi... hiện toàn bộ
Neutron density fluctuation and neutron–proton correlation from AMPT model
Springer Science and Business Media LLC - Tập 58 - Trang 1-5 - 2022
Zuman Zhang, Ning Yu, Hongge Xu
Using the multiphase transport (AMPT) model, we study the relative neutron density fluctuation and neutron–proton correlation in matter produced by Au + Au collisions at $$\sqrt{s_\text {NN}}= $$ 7.7–200 GeV. The rapidity, centrality, and energy dependence of these two observations are also discussed. The light nuclei yield ratio of proton, deuteron, and triton $$N_tN_p/N_d^2$$ calculated directly... hiện toàn bộ
Isospin symmetry breaking in ρ→πγ decay
Springer Science and Business Media LLC - Tập 14 Số 2 - Trang 219-224 - 2002
Wang, X.-J., Jiang, J.-H., Yan, M.-L.
In terms of effective field theory and mixed-propagator approach, we show that there is a larger hidden effect of isospin breaking in ρ→πγ decay due to a ω exchange, ρ→ω→πγ. The branching ratio is predicted as B(ρ→πγ) = (11.67±2.0)×10-4, which is much larger than Particle Data Group's datum (6.8±1.7)×10-4 and one of charged mode, B(ρ±→π±γ) = (4.5±0.5)×10-4.
