half-integral1903

1903 Acta Mathematica 27 147 If we allow the formula which expresses a theta function of any characteristic, not necessarily half-integral, by the addition of certain constants.., we see that the equations are satisfied by sigma functions of quite arbitrary characteristic.

1968 M. S. Livingston Particle Physics ii. 24 Nuclei with an odd number of protons plus electrons, each with half-integral spin, should result in half-integral nuclear angular momenta.

2010 Guardian (Nexis) 14 Sept. (G2 section) 17 I carry on writing for myself about the separation between two reflected light waves being a half-integral number of wavelengths causing destructive interference.
