DEFINITION

Classification: 310/301

Nuclear reaction:

(under subclass 300) Subject matter relating to the obtaining of energy in the electrical state from the internal energy of the atom.

(1) Note. This subclass relates, for example, to electric generators consisting of radioactive sources which acquire a charge due to the emission of electrons or other ionized particles at such a high speed as to go through a considerable adverse electric gradient before being collected.
