Chirality-asymmetry force between \alpha-quartz and copper block

The chirality-asymmetry macroscopic force mediated by light pseudoscalar particles between \alpha -quartz and some achiral matter is studied. If this force between achiral source mass and \alpha -quartz with some chirality is attractive, it will become repulsive when the chirality of the \alpha -quartz crystal is changed. According to the tested limits of the coupling constant g_\rm s g_\rm p / \hbar c < 1.5\times 10^ - 24 at the Compton wavelength \lambda = 10^ - 3\,m, the force (F) between a 0.08\times 0.08\times 0.002\,m^3 block of \alpha -quartz and a 0.08\times 0.08\times 0.01\,m^3 copper block with a separation being 0.5\times 10^ - 3\,\mboxm in between, is estimated from the published data at less than 4.64\times 10^ - 24\,\mboxN, i.e. F < 4.64\times 10^ - 24\,\mboxN.
