Abstract

Coulomb excitation of the exotic neutron-rich nucleus ²⁶Ne on a ²⁰⁸Pb target was measured at 58 A.MeV in order to search for low-lying E1 strength above the neutron emission threshold. Data were also taken on an Al target to estimate the nuclear contribution. The radioactive beam was produced by fragmentation of a 95 A.MeV Ar beam delivered by the RIKEN Research Facility. The set-up included a NaI gamma-ray array, a charged fragment hodoscope and a neutron wall. Using the invariant mass method in the ²⁵Ne+n channel, we observe a sizable amount of E1 strength between 6 and 10 MeV excitation energy. By performing a multipole decomposition of the differential cross-section, a reduced dipole transition probability of B(E1)=0.49±0.16 e²fm² is deduced. For the first time, the decay pattern of low-lying strength in a neutron-rich nucleus is measured.
