Abstract
A family of four odd parity bands in 127Xe has been investigated via in-beam γ-ray spectroscopy and conclusive evidence for the first and second phonon longitudinal wobbling excitations has been found. Spectroscopic measurements confirm the predominant E2 character of the ΔI=1 transitions between the wobbling bands. This provides the first experimental evidence of longitudinal wobbling mode associated with a neutron configuration.
