Abstract
For a continuous super-Brownian reactant X in Rd with general catalyst ρ a Brownian snake representation is derived for the part Xc of X in the catalyst region. This extends results of Dawson et al. (2002) and Klenke (2003) in that it allows the collision local time of an intrinsic reactant particle with the catalyst to have flat pieces, caused by catalyst-free regions.
