  We study quasi-one-dimensional atomic gases across wide and narrow
confinement-induced-resonances (CIR). We show from Virial expansion that by
tuning the magnetic field, the repulsive scattering branch initially prepared
at low fields can continuously go across CIR without decay; instead, the decay
occurs when approaching the non-interacting limit. The interaction properties
essentially rely on the resonance width of CIR. Universal thermodynamics holds
for scattering branch right at wide CIR, but is smeared out in narrow CIR due
to strong energy-dependence of coupling strength. In wide and narrow CIR, the
interaction energy of scattering branch shows different types of strong
asymmetry when approaching the decay from opposite sides of magnetic field.
Finally we discuss the stability of repulsive branch for a repulsively
interacting Fermi gas in different trapped geometries at low temperatures.
