The lowest six excited 2{sup +} levels of the even-even {sup 122-130}Te nuclei have been investigated using {gamma}-ray spectroscopy following inelastic neutron scattering. These levels have been identified and their decay properties have been characterized from {gamma}-ray excitation functions and {gamma}-ray angular distributions; additionally, lifetimes of these levels have been deduced using the Doppler-shift attenuation method. Electromagnetic transition rates and E2/M1 multipole mixing ratios from the 2{sub x}{sup +}[x=2-6]{yields}2{sub 1}{sup +} transitions have been examined to identify the lowest mixed-symmetry states in these nuclei. In each nucleus, the mixed-symmetry strength appears to be fragmented between more than one level. The summed M1 strength from the 2{sub x}{sup +}[x=2-6] states to the 2{sub 1}{sup +} level agrees rather well with neutron-proton interacting boson model predictions in the U(5) or O(6) limits for these Te nuclei.
