Levels of ^120Te Using the ^118Sn(α,2nγ) Reaction and ^120I β-decay
Abstract
The level scheme of ^120Te has been developed following in-beam γ-ray spectrosopy performed at the Paul Scherrer Institut's Phillips Cyclotron. Excitation functions, γ-γ coincidences, and angular distributions were measured following the ^118Sn(α,2nγ) reaction. Additionally, γ-γ coincidences were measured following ^120I beta-decay from in-beam activated samples. Spectroscopic information is obtained for approximately 60 new levels below 3.4 MeV excitation. Tellurium-120 appears to have many characteristics of a harmonic vibration nucleus. It is known, however, that other configurations such as particle and intruder structures play an important role in neighboring nuclei. Results provide information on the behavior of multiphonon configurations in softly deformed potentials, the interplay of particle and collective structures, and the apparent lack of intruder configurations in the heavier tellurium nuclei.
