THE STRUCTURE OF THE ALGEBRA OF OBSERVABLES IN THE INTERMEDIATE SITUATION OF THE EPSILON-MODEL

We look at the action of the spin-1/2 operators of quantum mechanics o n the state of an entity in a physical way, and use this as a guidelin e Lo define the operators of the intermediate situations of a general spin-1/2 measurement model called the epsilon-model. Then we test the possible linearity of the operators so constructed.
