    Evidence of a proton halo in Al: A mean field analysis

    R. N. Panda · M. Panigrahi · Mahesh K. Sharma · S. K. Patra

    We have studied the nuclear structure properties like binding energy, charge radius, quadrupole deformation parameter for various isotopes of Al from the valley of stability to drip line region using the well known relativistic mean field formalism (RMF) with NL3 parameter set. We have compared our results with experimental data and found reasonable agreement. Further, we have taken spherical and deformed RMF densities to estimate the reaction dynamics of Al isotopes as projectiles and C as target by conjunction in Glauber model. The estimated results are also compared with the experimental data. The analysis of angular elastic differential and one proton removal cross sections are also studied with Glauber model many body system to investigate the structural feature of Al. The evidence of enhanced total reaction cross section, higher value of rms radius, narrow longitudinal momentum distribution and small proton separation energy of Al support its proton halo structure.

    Behavior of universal critical parameters in the QCD phase diagram

    Marcus Bluhm (North Carolina State U.)🇺🇸 · Marlene Nahrgang (SUBATECH, Nantes and Duke U.)🇺🇸 · Steffen A. Bass (Duke U.)🇺🇸 · Thomas Schaefer (North Carolina State U.)🇺🇸

    We determine the dependence of important parameters for critical fluctuations on temperature and baryon chemical potential in the QCD phase diagram. The analysis is based on an identification of the fluctuations of the order parameter obtained from the Ising model equation of state and the Ginzburg-Landau effective potential approach. The impact of the mapping from Ising model variables to QCD thermodynamics is discussed.

    An effective two-body model for spectra of clusters of H, H, He, and He with He, and H-He scattering

    P. R. Fraser · K. Massen-Hane · A. S. Kadyrov · K. Amos · I. Bray · L. Canton

    Four light-mass nuclei are considered by an effective two-body clusterisation method; Li as HHe, Li as HHe, Be as HeHe, and Be as HeHe. The low-energy spectrum of each is determined from single-channel Lippmann-Schwinger equations, as are low-energy elastic scattering cross sections for the HHe system. These are presented at many angles and energies for which there are data. While some of these systems may be more fully described by many-body theories, this work establishes that a large amount of data may be explained by these two-body clusterisations.

    Study of shape coexistence in the 180-190Hg isotopes by SO(6) representation of eigenstates

    H. Sabri · O. Jabbarzade · A. Ghale Asadi · S. K. Mousavi Mobarake

    In this paper, we have studied the shapes coexistence in the 180-190Hg isotopes. The SO(6) representation of eigenstates and a transitional Hamiltonian in the Interacting Boson Model are used to consider the evolution from prolate to oblate shapes for systems with total boson number N = 9-12. Parameter free (up to overall scale factors) predictions for energy spectra and quadrupole transition rates are found to be in good agreement with experimental counterparts. The results for the control parameter of transitional Hamiltonian offer a combination of spherical and deformed shapes in these Hg isotopes and also more deviation from SO(6) limit is observed when the quadrupole deformation is decreased. Also, there are some suggestion about the expectation values of operator which are determined in the first state of ground, beta and gamma bounds and the control parameter of model.
