We investigate the existence, stability and propagation dynamics of spatial solitons supported by an interface separating 1D different-order Bessel optical potentials. The profiles of surface solitons are determined by the order and the modulation depth of Bessel potential. Influences of the order and modulation depth of Bessel potential besides the interface on the stability of surface solitons are discussed. We show that the surface solitons supported by present model have a wide stability region in their existence domain even for higher-order Bessel potential or the difference of the order of Bessel function on the opposite side of the interface is relatively large (e.g. nl = 2, nr = 5). The experimental realization of the model we discussed is also proposed. Numerical simulation of the propagation of surface solitons verifies our stability analysis. This study may enrich the concept of optical surface soliton.
