摘　　要：We study multi-skyrmion states using the Skyrme model with a false vacuum potential up to baryon number B=8 using the product ansatz. It is found that both the false and true vacuum potentials can result in a cluster structure for the multi-skyrmion states. We also analyze the effect of explicit chiral breaking on the masses and contour surfaces of the baryon number density of the multi-skyrmion states.
