Coexisting structures in the 120-124Te nuclei

The level schemes of the mid-shell tellurium nuclei, A = 120-124, have been developed utilizing in-beam γ-ray spectroscopy following the (n, n'γ) and (α,2nγ) reactions and iodine beta decay. Excitation functions, γ - γ coincidences, and angular distributions were measured. Spectroscopic information is obtained for many new levels below 4.5 MeV excitation. Low-spin states are found to be a mixture of spherical-vibrational, two-particle, and intruder configurations. The emerging intruder band is identified in 120Te. The situation in 122Te and 124Te is not quite as clear. (author)
