  Using the density matrix renormalization group (DMRG), we study the 2D t-J
model at a hole doping of x=1/8 on clusters as large as 19x8. We find a striped
phase which is consistent with recent neutron scattering experiments. We find
that bond-centered and site-centered stripes have nearly the same energy,
suggesting that in the absence of pinning effects the domain walls can
fluctuate.
