Evidence for octupole correlation in Z=50 Sn isotopes: Spectroscopy of ¹¹²Sn

NUCLEAR REACTIONS ¹⁰³Rh(¹²C, 2np)¹¹²Sn, E=62 MeV; measured Eγ, Iγ, γγ-coin. ¹¹²Sn; deduced levels, J, π, δ, high-spin states, T_1/2 of excited states, intruder rotational bands, B(E2), B(E1), configurations, energy displacement between positive and negative parity bands. Systematics of B(E1) and levels structure for ¹¹²Sn, ²²⁶Ra, ¹¹²Xe, ¹¹⁴Xe, ¹¹⁶Xe, ¹¹⁸Xe. Confirmed octupole correlations in ¹¹²Sn with relativistic Hartree-Bogoliubov (RHB) calculations. Setup consisting of 17 Compton-suppressed HPGe detectors and 5 Compton-suppressed clover detectors at the Heavy Ion Research Facility in LanZhou (HIRFL).

NUCLEAR STRUCTURE ¹¹²Sn; calculated single-neutron levels as functions of deformation parameters. Calculations wit relativistic Hartree-Bogoliubov (RHB) model based on PC-PK1 energy density functional.
