  We give a correct tensor proof of the positive energy problem for the case
including momentum on basis of conditions of existence of the two-to-one
correspondence between the Sen-Witten spinor field and the Sen-Witten
orthonormal frame. These conditions were obtained in our previous publications,
but true significance of our works was not estimated properly by G.Y.Chee, and
these were not correct quoted in his publication. On other hand, the main
result of our work is key argument in favour of geometrical nature of the
Sen-Witten spinor field.
