    "abstract": "It is shown that the spin of pi (0), eta, Lambda, Sigma (+,-,0), Xi (-,0),\nLambda-c (+), Sigma-c (0), Xi-c (0), and Omega-c (0) mesons and baryons can be\nexplained by the sum of the angular momentum vectors and spin vectors of the\nelectromagnetic waves which are in these particles according to the standing\nwave model. The spin of the pi (+,-), K (+,-,0), D (+,-,0), and D-S (+,-)\nmesons and of the neutron is the sum of the angular momentum vectors of the\noscillations and of the spin vectors of the neutrinos and the electric charges\nwhich are in the cubic lattice of these particles. Spin 1/2 is the consequence\nof the superposition of two perpendicular standing waves of equal frequencies\nand amplitudes shifted in phase by pi/2. The spin of the antiparticles of the\nmesons and baryons is the same as the spin of the ordinary particles.",
