Query: Domain Walls in Kaluza-Klein spacetime   Three families of exact solutions of Einstein field equations are found. Each
family contains three parameters. Two of these families represent thick domain
walls in a five dimensional Kaluza-Klein spacetime. The dynamical behaviour of
our models is briefly discussed. The spacetime in all the cases is found to be
reflection symmetric with respect to the wall.
