  In the QCD-inspired potential model where the quark-antiquark interaction
consists of the usual one-gluon-exchange and the mixture of long-range scalar
and vector linear confining potentials with the lowest order relativistic
correction, we investigate the mass spectra and electromagnetic processes of a
bottomonium system by using the Gaussian expansion method. It reveals that the
vector component of the mixing confinement is anticonfining and takes around
18.51% of the confining potential. Combining the new experimental data released
by Belle, BaBar and LHC, we systematically discuss the energy levels of the
bottomonium states and make the predictions of the electromagnetic decays for
further experiments.
