Outstanding problems in the band structures of $^{152}\mathrm{Sm}$


Author(s): J. B. Gupta and J. H. Hamilton

The recent data on $B(E2)$ values, deduced from the multi-Coulex excitation of the low spin states in the decay of $^{152}\mathrm{Sm}$, and other experimental findings in the last two decades are compared with the predictions from the microscopic dynamic pairing plus quadrupole model of Kumar and Ba...

Shadowing in low-energy photonuclear reactions


Author(s): Swapan Das

The photonuclear reaction in the multi-GeV region occurs because of the electromagnetic and hadronic interactions. The latter originates due to the hadronic fluctuation, i.e., vector meson, of the photon. The total cross section of the reaction is shadowed because of the vector meson–nucleus (hadron...

Interdependence of different symmetry energy elements


Author(s): C. Mondal, B. K. Agrawal, J. N. De, S. K. Samaddar, M. Centelles, and X. Viñas

Relations between the nuclear symmetry energy coefficient and its density derivatives are derived. The relations hold for a class of interactions with quadratic momentum dependence and a power-law density dependence. The structural connection between the different symmetry energy elements as obtaine...

Systematic study of unfavored $α$-decay half-lives of closed-shell nuclei related to ground and isomeric states


Author(s): Jun-Gang Deng, Jie-Cheng Zhao, Dong Xiang, and Xiao-Hua Li

In the present work, the unfavored $α$-decay half-lives and $α$ preformation probabilities of closed-shell nuclei related to ground and isomeric states around $Z=82, N=82$ and 126 shell closures are investigated by adopting the two-potential approach from the perspective of valence nucleon (hole) an...

Measurements of long-range azimuthal anisotropies and associated Fourier coefficients for $pp$ collisions at $\sqrt{s}=5.02$ and 13 TeV and $p+\text{Pb}$ collisions at $\sqrt{{s}_{\mathrm{NN}}}=5.02$ TeV with the ATLAS detector


Author(s): M. Aaboud et al. (ATLAS Collaboration)

ATLAS measurements of two-particle correlations are presented for $\sqrt{s}=5.02$ and 13 TeV $pp$ collisions and for $\sqrt{{s}_{\mathrm{NN}}}=5.02$ TeV $p+\text{Pb}$ collisions at the LHC. The correlation functions are measured as a function of relative azimuthal angle $\mathrm{Δ}ϕ$, and pseudorapi...
