High-sensitivity investigation of low-lying dipole strengths in ¹²⁰Sn

NUCLEAR REACTIONS ¹²⁰Sn(γ, γ'), E=9.5 MeV bremsstrahlung beam; measured Eγ, Iγ, γ(θ) using four HPGe detectors at the γELBE facility of Helmholtz-Zentrum Dresden-Rossendorf. ¹²⁰Sn; deduced levels, pygmy dipole resonances (PDR), J, π, Γ₀²/Γ, photoabsorption σ(Eγ), B(E1), Thomas-Reiche-Kuhn sum rule using statistical model with constant-temperature level density. Comparison with experimental results for ¹²⁰Sn(p, p').
