The level scheme of 134Cs

Low-lying states in 134Cs have been investigated using the 133Cs(n, γ)134Cs and 133Cs(d, p)134Cs reactions with various spectroscopic techniques. Numerous excited states in 134Cs have been established with energies up to 1267 keV. The experimental data on the lowest negative- and positive-parity states are in fair agrement with the calculations based on two quasiparticles coupled to a vibrator. For higher excited states the multiplets appear more mixed than predicted by the simple model.
