We explore a particular approach to study D-brane boundary states inBerkovits' pure spinor formalism of superstring theories. In this approach oneconstructs the boundary states in the relevant conformal field theory byrelaxing the pure spinor constraints. This enables us to write down the openstring boundary conditions for non-BPS D-branes in type II string theories,generalizing our previous work in light-cone Green-Schwarz formalism. As afirst step to explore how to apply these boundary states for physicalcomputations we prescribe rules for computing disk one point functions for thesupergravity modes. We also comment on the force computation between twoD-branes and point out that it is hard to make the world-sheet open-closedduality manifest in this computation.Comment: 26 pages.
