| Abstract: | The Theory of angular momentum waves in pure ortho-hydrogen is presented in the Bloch spin wave approximation. Since there is a large energy gap between the ground state and the excitation this approximation can be justified. Quadrupole-quadrupole interaction of nearest neighbours is used. We have derived some dispersion curves and the spectrum. |
