Abstract
The properties of the 2+1 and 2+2 excited states in 14C were studied in an experiment conducted at the Argonne National Laboratory. A 9Be(6Li, pγ) fusion–evaporation reaction and the GRETINA–ORRUBA setup were employed to populate states of 14C and detect γ-particle coincidence events. The precise determination of the 2+1 level energy, complemented by the estimation of the γ-ray branch of the 2+2 near-threshold state, will serve as a benchmark to test the Shell Model Embedded in the Continuum calculations.
