Based on tilted axis cranking relativistic mean-field theory within point-coupling interaction PC-PK1,the rotational structure and the characteristic features of antimagnetic rotation for △I=2 bands in~(108,110)In are studied.Tilted axis cranking relativistic mean-field calculations reproduce the experimental energy spectrum well and are in agreement with the experimental I~ω plot,although the calculated spin overestimates the experimental values.In addition,the two-shears-like mechanism in candidate antimagnetic rotation bands is clearly illustrated and the contributions from two-shears-like orbits,neutron(gd)orbits above Z=50 shell and Z=50,N=50 core are investigated microscopically.The predicted B(E2),dynamic moment of inertia J~((2)),deformation parameters β and γ,and J~((2))/B(E2) ratios in tilted axis cranking relativistic mean-field calculations are discussed and the characteristic features of antimagnetic rotation for the bands before and after alignment are shown.
Based on tilted axis cranking relativistic mean-field theory within point-coupling interaction PC-PK1, the rotational structure and the characteristic features of antimagnetic rotation for △ I = 2 bands in ~ (108,110) In are studied. Titled axis cranking relativistic mean- field calculations reproduce the experimental energy spectrum well and are in agreement with the experimental I ~ ω plot, although the calculated spin overestimates the experimental values. In addition, the two-shears-like mechanism in candidate antimagnetic rotation bands is clearly illustrated and the contributions from two-shears-like orbits, neutron (gd) orbits above Z = 50 shell and Z = 50, N = 50 cores are microscopically.The predicted B (E2) deformation parameters β and γ, and J ~ (2) / B (E2) ratios in tilted axis cranking relativistic mean-field calculations are discussed and the characteristic features of antimagnetic rotation for the bands before and after alignment are shown.
