The structure of the doubly magic $_{50}^{132}\mathrm{Sn}_{82}$ has been investigated at ISOLDE facility CERN, populated both by ${\ensuremath{\beta}}^{\ensuremath{-}}\phantom{\rule{0.28em}{0ex}}\mathrm{decay}$ $^{132}\mathrm{In}$ and ${\ensuremath{\beta}}^{\ensuremath{-}}$-delayed neutron emission $^{133}\mathrm{In}$. level scheme $^{132}\mathrm{Sn}$ is greatly expanded with addition 68 $\ensuremath{\gamma}$ transitions 17 levels observed for first time in $\ensuremath{\beta}$ decay. information on excited completed new states $\ensuremath{\beta}\text{\ensuremath{-}}n$ decay Improved delayed probabilities are obtained Level lifetimes measured via advanced time-delayed $\ensuremath{\beta}\ensuremath{\gamma}\ensuremath{\gamma}$(t) fast-timing method. An interpretation given based experimental findings particle-hole configurations arising from core excitations $N$ = 82 $Z$ 50 shells, leading to positive- negative-parity multiplets. provides data challenge theoretical description $^{132}\mathrm{Sn}$.
