Measurement of the 2⁺₁ level lifetime in ¹²⁰Sn by the Doppler shift attenuation method: Evidence of enhanced collectivity

NUCLEAR STRUCTURE ¹²⁰Sn(³²S, ³²S')¹²⁰Sn^*, E=120 MeV; measured Eγ, Iγ, γ(θ) using enriched target and INGA array of 11 Compton-suppressed HPGe detectors, half-life of the first 2+ level in ¹²⁰Sn from DSAM at the BARC-TIFR Pelletron LINAC facility. ¹²⁰Sn; deduced level, B(E2) for the first 2+ state, enhanced collectivity, anharmonic nature of quadrupole vibrations; compiled experimental B(E2) values for the first 2+ states in ^{112,114,116,118,120,122,124}Sn.
