First Edition
1st Edition. FIRST EDITION IN ORIGINAL WRAPPERS of a paper in which Murray Gell-Mann and Abraham Pais make an interesting prediction about the decay of the kaon. A paper by Francis Low is also included (more below). "Murray Gell-Mann and Abraham Pais (1955) used an argument based on C invariance. to discuss the production and decay of a particle known as the neutral K meson, or K0. This particle, according to a theory by Gell-Mann and Kazuo Nishijima, carried a quantum number called strangeness, with S(K0 ) = +1, and so there should exist a neutral anti-K meson, called K 0 , with S(K 0 ) = -1. The theory demanded that strangeness be conserved in K-meson production but violated in its decay. Both the K0 and the K0 should be able to decay to a pair of mesons (e.g., + ). How, then, would one tell them apart? Gell-Mann and Pais solved this problem by applying a basic idea of quantum mechanics: The particle decaying to + would have to have the same behavior under C (in 1957, under CP) as the final + combination, which has CP = +1. (That is, its quantum-mechanical state is taken into itself under the CP operation.) A quantum-mechanical combination of K0 and K 0 with this property was called K0 1 . There should then exist another combination of K0 and K 0 with CP = -1 (i.e., its quantum-mechanical state is changed in sign under the CP operation). This particle was called K0 2 . (The subscripts 1 and 2 were used simply to distinguish the two particles from one another.) The 2 K0 2 would be forbidden by CP invariance from decaying to and thus, being required to decay to three-body final states, would be much longer-lived. This predicted particle was discovered in 1956" (Rosner, CP Symmetry Violation, 1). In 1969 Gell-Man was awarded a Nobel Prize in Physics "for his work in classifying elementary particles and their interactions." FRANCIS LOW PAPER: "It is shown that the S-matrix for boson-fermion scattering can be simply expressed in the Heisenberg representation. By performing a time integration one obtains the S-matrix in the Schrödinger representation, which has the same form as the conventional perturbation theory sum over states. Suitably limiting the nature of the intermediate states entering into this sum leads to integral equations for certain matrix elements which are equal to the S-matrix elements on the energy shell. These equations appear in a completely renormalized form" (Abstract). CONDITION & DETAILS: 1st ed. original wrappers. Complete issue paginated 1191-1417. 4to (10.5 x 8 inches; 263 x 200mm). The wrappers are perfect save for a stamp on front wrap; the interior has barely visible toning upper right margin of some pages.

1st Edition. FIRST EDITION IN ORIGINAL WRAPS OF 3 SIGNIFICANT PAPERS: GELL-MANN & LOW'S THEOREM, STERNHEIMER ON SHIELDING & ANTI-SHIELDING, & SCHWINGER ON PHENOMENOLOGICAL NEUTRON-PROTON INTERACTION. GELL-MANN & LOW: Tackling formalism and the bound-state problem, Gell-Mann and Low's paper is Nobel Prize winner Gell-Mann's first published paper. The theorem and formal derivation they achieve is a "cornerstone in quantum field theory and zero-temperature many-body theory" (Molinari, Journal of Mathematics, 48, 2007). In quantum field theory, the Gell-Mann and Low theorem "allows one to relate the ground (or vacuum) state of an interacting system to the ground state of the corresponding non-interacting theory. The theorem is useful because, among other things, by relating the ground state of the interacting theory to its non-interacting ground state, it allows one to express Green's functions (which are defined as expectation values of Heisenberg-picture fields in the interacting vacuum) as expectation values of interaction picture fields in the non-interacting vacuum. While typically applied to the ground state, the Gell-Mann and Low theorem applies to any eigenstate of the Hamiltonian. Its proof relies on the concept of starting with a non-interacting Hamiltonian and adiabatically switching on the interactions"; the proof is based on Dyson's time-ordered expansion of the propagator; a proof based on exact identities for the time propagator is here given" (Wikipedia; Molinari). STERNHEIMER: Physicists knew that electrons of any given ion interacted with the quadrupolar field of the nucleus as well as with the local electrostatic potential. With respect to NMR issues, though, an important question remained: "What part of the energy of the system ion plus nuclear quadrupole moment plus local field depends on the orientation of the nucleus?" (Solid State Physics, 5, 347). Sternheimer was the first to study questions of this nature. Sternheimer found that "a perturbing potential, whether originating within an ion or outside it, polarizes the spherically symmetric complete shells of electrons. The complete shells, having thus lost their spherical symmetry, contribute destructively (shielding) or constructively (antishielding) to the perturbing potential at any site. The reduction or enhancement of the perturbing potential, the so called Sternheimer effect, could be accounted for in terms of some parameters" (Dekeyser, Electron Emission Spectroscopy, 250). To this day, the two Sternheimer shielding factors are still taken into account when core electrons are near an electric field gradient, Sternheimer shielding and anti-shielding factors. One is "associated with charges which are on the atom (or ion) in question, and one associated with more distant charges" (Vij, Handbook, 92). SCHWINGER & FESHBACH: "This paper describes the calculations and results obtained in fitting a phenomenological interaction to the properties of the deuteron and related low energy phenomena" (Schwinger and Feshbach, Phys. Rev. 84, 194). Together, Schwinger and Feshbach "solved the problem of the deuteron ground state and numerically calculated the quadrupole moment, effective range and relative probabilities for the system remaining in a D-angular momentum state, as well as the cross sections for photoelectric disintegration of deuterons" (Mehra, Climbing the Mountain, 163). While their calculations are now mainly of "historical interest only", Schwinger and Feshbach made their calculations on Harvard's first â??computing machine' - an IBM Automatic Sequence Controlled Calculator/Mark I; as well, they were among the first to use it (ibid). That machine is now on display in Harvard's Science Center. CONDITION & DETAILS: Lancaster: American Physical Society. Original wraps, complete.
