The Doppler-shift attenuation method following inelastic neutron scattering was used to determine the lifetimes of nuclear levels to 3.3-MeV excitation in 124 Te. Level energies and spins, γ -ray energies and branching ratios, and multipole-mixing ratios were deduced from measured γ -ray angular distributions at incident neutron energies of 2.40 and 3.30 MeV, γ -ray excitation functions, and γ γ coincidence measurements. The newly obtained reduced transition probabilities and level energies for
