Coulomb excitation of 2868Ni40 at ``safe'' energies
Abstract
The B(E2;0+→2+) value in Ni68 has been measured using Coulomb excitation at safe energies. The Ni68 radioactive beam was postaccelerated at the CERN on-line isotope mass separator (ISOLDE) facility to 2.9 MeV/u and directed to a Pd108 target. The emitted γ rays were detected by the MINIBALL detector array. Not only directly registered but also indirectly deduced information on the nucleus emitting the γ ray was used to perform the Doppler correction, leading to a larger center-of-mass angular range to infer the excitation cross section. The obtained value of 2.8-1.0+1.2×102e2fm4 is in good agreement with the value measured at intermediate energy Coulomb excitation, confirming the low 0+→2+ transition probability.
