Description
Excited states of 26Na were the subject of a Coulomb excitation experiment at REX-ISOLDE employing a radioactive 26Na beam with a final energy of 2.82 MeV/u. De-excitation gamma-rays were detected by the MINIBALL gamma-spectrometer in coincidence with scattered particles in a CD-shaped segmented Si-detector. Reduced transition matrix-elements for the excited states of 26Na at 233 keV and 407 keV were determined for the first time. The obtained values are compared to theoretical predictions from updated shell model calculations using USDA/USDB interactions.
