New lifetime measurement for the 2⁺₁ level in ¹¹²Sn by the Doppler-shift attenuation method

NUCLEAR REACTIONS ¹¹²Sn(³⁵Cl, ³⁵Cl'), E=195 MeV; measured Eγ, Iγ, γγ-coin, half-lives of the first 2+ and 3- states from Doppler broadening using INGA array at BARC-TIFR Pelletron LINAC Facility. ¹¹²Sn; deduced levels, J, π, B(E2), B(E1); calculated potential energy surface in (Q₂, Q₄) plane using Q-constrained Hartree-Fock method. Comparison with previous measurements, and with generalized seniority model (GSM) and state-of-the-art Monte Carlo shell model (MCSM) calculations. Systematics of B(E2) for the first 2+ states in A=112-124 Sn nuclei.
