PATH-INTEGRAL QUANTIZATION OF A SPINNING PARTICLE

Barut's classical model of the spinning particle having external dynam ical variables x and p and internal dynamical variables (z) over bar a nd z is taken into account. The path integrations over holomorphic spi nors (z) over bar and z are discussed. This quantization gives the ker nel of the relativistic particles with higher spin as well as the Dira c electron. The Green's function of the spin-n/2 particle is obtained.
