Plaque at Fermi's birthplace. Enrico Fermi was born in Rome, Italy, on 29 September 1901. [3] He was the third child of Alberto Fermi, a division head in the Ministry of Railways, and Ida de Gattis, an elementary school teacher. [3] [4] [5] His sister, Maria, was two years older, his brother Giulio a year older.
In 1934, Enrico Fermi published his classic paper describing the process of beta decay, in which the neutron decays to a proton by creating an electron and a (as yet undiscovered) neutrino. [75] The paper employed the analogy that photons , or electromagnetic radiation, were similarly created and destroyed in atomic processes.
This contained deuterium, which would not absorb neutrons like ordinary hydrogen, and was a better neutron moderator than carbon; but heavy water was expensive and difficult to produce, and several tons of it might be needed. [27] Fermi estimated that a fissioning uranium nucleus produced 1.73 neutrons on average.
The discovery of the neutron by James Chadwick in 1932 created a new means of nuclear transmutation. Enrico Fermi and his colleagues in Rome studied the results of bombarding uranium with neutrons, and Fermi concluded that his experiments had created new elements with 93 and 94 protons, which his group dubbed ausenium and hesperium.
The X-10 Graphite Reactor is a decommissioned nuclear reactor at Oak Ridge National Laboratory in Oak Ridge, Tennessee.Formerly known as the Clinton Pile and X-10 Pile, it was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile-1) and the first intended for continuous operation.
The FERMIAC, or Monte Carlo trolley, was an analog device invented by Enrico Fermi to implement studies of neutron transport. The Monte Carlo trolley, or FERMIAC, was an analog computer invented by physicist Enrico Fermi to aid in his studies of neutron transport. [1]
Via Panisperna boys (Italian: I ragazzi di Via Panisperna) is the name given to a group of young Italian scientists led by Enrico Fermi, who worked at the Royal Physics Institute of the University of Rome La Sapienza. In 1934 they made the famous discovery of slow neutrons.
Fermi first introduced this coupling in his description of beta decay in 1933. [3] The Fermi interaction was the precursor to the theory for the weak interaction where the interaction between the proton–neutron and electron–antineutrino is mediated by a virtual W − boson, of which the Fermi theory is the low-energy effective field theory.
