Here, we consider nuclear excitation by electron capture (NEEC) in a beam-based experiment for the Rb84m isomer (Iπ = 6−, T1/2=20.26 min). The NEEC process for the Rb84m isomer allows an excitation by magnetic-dipole (M1) and electric-quadrupole (E2) transitions into a depletion level (Iπ = 5−), which subsequently decays, releasing a substantial amount of stored energy. To ensure effective production of the Rb84m isomer, the fusion-evaporation reaction Se82 + Li7 is considered.
