This volume presents, with some amplification, the notes on the lectures on nuclear physics
given by Enrico Fermi at the University of Chicago in 1949." The compilers of this publication
may be warmly congratulated.... The scope of this course is amazing: within 240 pages it …

a package of our theoretical graphs to show to Fermi. When I arrived in Fermi's office, I
handed the graphs to Fermi, but he hardly glanced at them. He invited me to sit down, and
asked me in a friendly way about the health of my wife and our newborn baby son, now fifty …

Student, collaborator and lifelong friend of Enrico Fermi, Emilio Segrè presents a rich, well-
rounded portrait of the scientist, his methods, intellectual history, and achievements.
Explaining in nontechnical terms the scientific problems Fermi faced or solved, Enrico Fermi …

A theory of the origin of cosmic radiation is proposed according to which cosmic rays are
originated and accelerated primarily in the interstellar space of the galaxy by collisions
against moving magmetic fields. One of the features of the theory is that it yields naturally an …

In 1938, at the age of 37, Enrico Fermi was awarded the Nobel Prize in Physics. That same
year he emigrated from Italy to the United States and, in the course of his experiments,
discovered nuclear fission--a process which forms the basis of nuclear power and atomic …

A statistical method for computing high energy collisions of protons with multiple production
of particles is discussed. The method consists in assuming that as a result of fairly strong
interactions between nucleons and mesons the probabilities of formation of the various …

A detailed discussion of the energy loss of negative mesotrons in matter is presented. The
energy range considered is from+ 2000 ev to the lowest quantized orbit of the mesotron. The
most important mechanism for energy loss is that of electron collisions except very near the …

It is shown that the loss of energy of a fast charged particle due to the ionization of the
material through which it is passing is considerably affected by the density of the material.
The effect is due to the alteration of the electric field of the passing particle by the electric …

ABSTRACT A one-dimensional dynamical system of 64 particles with forces between
neighbors containing nonlinear terms has been studied on the Los Alamos computer
MANIAC I. The nonlinear terms considered are quadratic, cubic, and broken linear types …
