On the lifetime of the 2+ state in 10C

Abstract

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.
