  Two newly observed bands built on a two-quasiparticle configuration in 130Ba
have been investigated for the first time with the microscopic projected shell
model. The experimental energy spectra and the available electromagnetic
transition probabilities are well reproduced. The wobbling character of the
higher band is revealed by the angular momentum projected wavefunctions via the
K plot and the azimuthal plot. This provides the first strong microscopic
evidence for wobbling motion based on a two-quasiparticle configuration in
even-even nuclei.
