The semi-magic $$^{110-122}$$Sn isotopes display signs of shape coexistence in their excited 0$$^{+}$$ states, which, in contrast to the spherical 0$$^{+}$$ ground states, are deformed. This paper investigates the nuclear structure of $$^{114}$$Sn using the competing $$beta$$$$^{+}$$ decay and electron capture of a radioactive beam of $$^{114}$$Sb produced at the TRIUMF-ISAC facility using the GRIFFIN spectrometer. This study will allow for an in-depth understanding of the excited 0$$^{+}$$ states in $$^{114}$$Sn, by focusing on their decay patterns. In the present experiment, transitions at 856.2-keV and 1405.0-keV, which were observed in an earlier $$beta$$$$^{+}$$ decay study but not placed in the $$^{114}$$Sn level scheme, have been assigned to the level scheme in connection to the 0$$^{+}$$ 3 level at 2156.0-keV. Properly assigning these transitions refines the level scheme and enhances our understanding of the nuclear structure in $$^{114}$$Sn.
