Chushiro Yonezawae situation had changed radically since March 1921, when he had last left the Italian capital. The March on Rome had ended in triumph for Mussolini. With his appointment as minister president on 30 October 1922, fascist rule had been consolidated. At the end of 1932 the domestic position of the ‘Duce’ was more or less unchallenged.

Principles of the PGAA method,f neutrons in hydrogenous materials, the emission of a highly penetrating gamma radiation was observed already in 1934 (Amaldi .. 1934, Lea 1934). This was the first prompt gamma radiation ever detected. Now we know it is the 2223.2487 keV energy prompt gamma ray from the reaction .H(n,γ).H.

Beams and Facilities,e beam on and off, a target assembly to position the sample reproducibly in the neutron beam, a gamma-ray detector, a beam stop to absorb the neutrons that are not absorbed by the sample, and shielding to protect the detector and personnel from neutron and gamma radiation. Each of these components will be considered in turn.

Gamma-Ray Spectrometry,The basic equipment for detection of prompt gamma rays is the gamma-ray spectrometer. The main component is the detector which converts the energy of the gamma ray to an electronic signal. This signal is amplified, shaped, digitized and stored in a histogram that makes up a spectrum of gamma peaks.
