Jones H, 1973, The electron energy spectrum in long period superlattices, Journal of Physics F: Metal Physics, Vol: 3, Pages: 2075-2081, ISSN: 0305-4608

The electron energy spectrum in a long period superlattice structure is investigated. It is shown that for a one dimensional model consisting of an array of delta functions it is possible to obtain the eigenvalues and wavefunctions exactly for all antiphase domain sizes. These results are used to examine the accuracy of calculations previously made by various approximate methods.

Jones HF, Scadron MD, Gault FD, 1970, Gauge invariance and covariant Reggeization, Il Nuovo Cimento A, Vol: 66, Pages: 424-436, ISSN: 0369-3546

By the use of gauge-invariant couplings the formalism of covariant Reggeization is extended to deal with processes involving photons. Particular attention is paid to pion photoproduction, where Reggeized pion and nucleon exchange are shown to connect smoothly on to the elementary exchanges both from the form of the vertex couplings and form their respective contributions to the invariant amplitudes. In the latter approach the double-pole structure of the Coulomb Born terms is correctly reproduced. Pion Compton scattering is also studied as an archetypal two-photon process: here the problem of Pomeron Reggeization is similarly resolved. The Froissart-Gribov continuation is briefly discussed, as is the forward peak in π+ photoproduction. © 1970, Società Italiana di Fisica. All rights reserved.

Jones HF, Scadron MD, 1968, Natural zeros of regge residues, Physical Review, Vol: 171, Pages: 1809-1810, ISSN: 0031-899X

We discuss the method of Reggeization of invariant amplitudes with particular reference to the kinematic zeros of the residue functions at nonsense points in J and at t=0. The zeros which occur naturally at these points yield in the first case the sense-choosing solution, and in the second case a well-defined scheme, covariant evasion, for satisfying the t=0 conditions on helicity amplitudes. Factorization is automatically satisfied in our method. © 1968 The American Physical Society.

Scadron MD, Jones HF, 1968, Covariant M functions for higher spin, Physical Review, Vol: 173, Pages: 1734-1744, ISSN: 0031-899X

We give a systematic treatment of high-spin M functions in the Dirac-Rarita-Schwinger formalism. The main difficulty in writing such M functions is that apparently independent covariants are in fact related. We derive these relations (equivalence theorems) and show how they may be used to obtain a kinematic-singularity-free expansion of the M function. Many examples are given and the general pattern is discussed. We also analyze the restrictions due to discrete symmetries and show how to choose invariant amplitudes whose discontinuities are given by unitarity. The connection with the helicity formalism is stressed throughout. © 1968 The American Physical Society.

Superconvergent sum rules are derived for πN*→πN*, two of which agree with U6,6 when saturated by N and N poles in the equal-mass limit. Saturation for physical masses gives G{cyrillic}N*=84 MeV. It is pointed out that those sum rules which agree with U6,6 for πN→πN* and πN*→πN* do so also for all analogous strange-particle reactions. The special status of these sum rules is discussed. © 1967 Società Italiana di Fisica.

Jones HF, 1965, Pion-nucleon resonances and the angular distribution in pion electroproduction, Il Nuovo Cimento A, Vol: 40, Pages: 1018-1033, ISSN: 0369-3546

Using the helicity formalism, we find the contributions from final states of definite spin and parity, together with the interference terms between different final-state contributions, to the angular distributions of pions electro-produced from protons. For a single resonant final state the azimuthal terms turn out to be particularly simple, and may well serve as a test for the spin of the resonance. We show that the angular distribution may be used to detect the possible presence of a p 1/2 resonant state in the energy region of the second resonance. © 1965 Società Italiana di Fisica.
