Query: On the lifetime of the 2+ state in 10C   The lifetime of the J=2+ state in 10C was measured using the Doppler Shift
Attenuation Method following the inverse kinematics p(10B,n)10C reaction at 95
MeV. The 2+ state, at 3354 keV, has tau = 219\pm(7)stat \pm(10)sys fs
corresponding to a B(E2) # of 8.8(3) e2fm4. This measurement,combined with that
recently determined for 10Be (9.2(3) e2fm4), provides a unique challenge to
abinitio calculations, testing the structure of these states, including the
isospin symmetry of the wave functions. Quantum Monte Carlo calculations using
realistic two- and three-nucleon Hamiltonians that reproduce the 10Be B(E2)
value generally predict a larger 10C B(E2) probability but with considerable
sensitivity to the admixture of different spatial symmetry components in the
wave functions, and to the three-nucleon potential used.
