Phys. Rev. Lett. 92, 062501 (2004) [4 pages]Anomalously Hindered E2 Strength B(E2;21+→0+) in 16CReceived 17 August 2003; published 12 February 2004 The electric quadrupole transition from the first 2+ state to the ground 0+ state in 16C is studied through measurement of the lifetime by a recoil shadow method applied to inelastically scattered radioactive 16C nuclei. The measured mean lifetime is 77±14(stat)±19(syst) ps. The central value of mean lifetime corresponds to a B(E2;21+→0+) value of 0.63e2 fm4, or 0.26 Weisskopf units. The transition strength is found to be anomalously small compared to the empirically predicted value. © 2004 The American Physical Society URL:
