Commemoration – Franco Rasetti started his career as a physicist in Pisa and then in Rome since 1927, where he was called by Orso Maria Corbino to be a member of the famous Via Panisperna group led by Enrico Fermi. Although he was for a long time identified as Fermi’s collaborator, Rasetti is to be considered one of the great experimental physicists of the last century. I presume that everybody remembers the experiments of the Panisperna group which led to the discovery of the properties of slow neutrons and paved the way for the exploitation of nuclear energy, but other results by Rasetti have given important contributions to the development of modern physics. In 1928-29, while working at Caltech, he determined the statistical behaviour of nitrogen nuclei. This result definitely proved that the atomic nucleus cannot contain electrons, and opened the way for the discovery of the neutron and for Pauli’s neutrino hypothesis and Fermi’s theory of beta decay. After emigrating to Canada in 1938, where he accepted an appointment to the Catholic University of Laval, Rasetti refused to take part in the nuclear weapon programme, an example which was not followed by many of his contemporaries. He decided to leave physics and to devote himself to his erstwhile interests in the natural world. He soon became a world authority on trilobites, and on alpine flora. Our sister institution, the Italian Lincei Academy, has recently reissued his magnificent atlas of alpine flowers. Rasetti returned briefly to physics in the seventies, when he engaged in Rome in the measurement of the refractive index of a gas of free electrons. Some of the techniques he developed on this occasion have become widely used in the diagnostics of plasmas. With Franco Rasetti disappears the last of the original members of our Pontifical Academy of Sciences, which were nominated on the occasion of its re-foundation in 1936.
