Abstract

Establishing how and when large N/Z values require modified or new theoretical tools is a major quest in nuclear physics. Here we report the first measurement of the lifetime of the 21+ state in the near-dripline nucleus C20. The deduced value of τ₂₁₊=9.8±2.8(stat)-1.1+0.5(syst)ps gives a reduced transition probability of B(E2;21+→0g.s.+)=7.5-1.7+3. 0(stat)-0.4+1.0(syst)e2fm4 in good agreement with a shell model calculation using isospin-dependent effective charges.
