1. An analysis system for the identification of certain contents of an object, the analysis system comprising: a neutron source that contains no radioactive material and that generates neutrons exclusively from a deuteron beam hitting a deuterium target material, such that neutrons leave the target material with an energy of approximately 2.5 MeV, the 2.5 MeV neutrons acting on the object and causing the emission of characteristic xcex3 quanta from atomic nuclei of said contents of the object, the neutron source producing neutron pulses at a predetermined cycle time with pulse widths of less than 100 microseconds;  a measurement apparatus that detects the emitted xcex3 quanta and attributes the detected signals to certain atomic nuclei and chemical compounds characteristic of explosives and chemical warfare agents, the measurement apparatus being configured in such a way that within a first measurement window and a second measurement window, respectively, it can detect xcex3 quanta emitted from the object due to inelastic neutron scattering and xcex3 quanta emitted from the object as a result of neutron capture; and  a portable frame to which the neutron source and the measurement apparatus are attached. 2.
