Abstract: (APS)
We have measured differential cross sections for elastic and inelastic scattering of Ne20 + Pb208 at a lab energy of 131 MeV. Inelastic data for exciting the Ne20 2+ (1.63 MeV) state and a group of states near 4.2 MeV are presented. The data are analyzed by a rotational-model coupled-channels calculation including the ground state, 2+,and 4+ states of Ne20. We obtain the values: transition moment B(E2↑)=(0.0330±0.0015) e2 b2, intrinsic hexadecapole moment Q40=(0.022±0.003) e2 b2, and static quadrupole moment for the Ne20 2+ state Q2=(−0.27±0.03) e b. The result for Q2 emphasizes a discrepancy with the rotational model and with various shell model calculations.
