“…This may be connected with the very broad energy spectrum of the incident neutron beam, which had a FWHM ≈ 100 MeV. At the Dubna synchrocyclotron the first measurements were carried out by Dzhelepov et al [29,30] in 1952 -1954 with a 380 MeV neutron beam. Somewhat surprisingly, the authors considered that their result, R np (0) = 0.20 ± 0.04, to be compatible with the UCRL measurements [5,28].…”

The available data on the forward charge exchange of nucleons on the deuteron up to 2 GeV per nucleon are reviewed. The value of the inclusive nd → pnn/np → pn cross section ratio is sensitive to the fraction of spinindependent neutron-proton backward scattering. The measurements of the polarisation transfer in d( n, p ){nn} or the deuteron analysing power in p( d, {pp})n in high resolution experiments, where the final nn or pp pair emerge at low excitation energy, depend upon the longitudinal and transverse spin-spin np amplitudes. The relation between these types of experiments is discussed and the results compared with predictions of the impulse approximation model in order to see what new constraints they can bring to the neutron-proton database.

“…0 ψ ψ 0 = 0. It is also shown [6] that the Gursey Instanton is a special case of a class of exact solutions of the Gursey Model (the Kortel Solutions [7]) found via the Heisenberg anzats. Additionally, for the purpose of the progress of quantum field theories, many works have been done on the both models [8,9].…”

“…Especially, this property of instantons plays an important role in explaining the imprisonment of quarks in particles [3,4]. † fatma.aydogmus@gmail.com; fatmaa@istanbul.edu.tr On the other hand, the spinor-type instanton solutions are found in both the conformally invariant pure spinor two-dimensonal Thirring model (Thirring Instanton) with the nonlinear ψ ψ 2 self-coupled term [5], and the four-dimensional conformally invariant pure spinor Gursey model (Gursey Instanton) with nonlinear ψ ψ 4 3 self-coupled spinor term [6] by the spontaneous symmetry breaking of the conformal invariance of ψ spinor field, i.e. 0 ψ ψ 0 = 0.…”

In our previous study, we have investigated the behaviours of spinortype instantons in two-dimensional conformally invariant pure spinor Thirring model in phase space. In this paper, we study the role of the coupling constant in the evolution of the four-dimensional spinor-type instantons in phase space via the Heisenberg ansatz. For this purpose, we consider the Gursey model is a four-dimensional conformally invariant pure spinor model with nonlinear self-coupled spinor term. The model proposed in 1956 as a possible basis for a unitary description of elementary particles (Heisenberg-Bohr dream). This study will also lead us to investigate the dependence of the behaviours of spinor-type instantons in phase space on quantum fractional spinor number as well as dimensions.

“…In 1964, Dzhelepov and colleagues' diffusion-chamber results, which indicated a greatly increased cross section for dld molecular formation at 240 K compared to the Carnegie Tech result at liquid-hydrogen temperatures, gave the first inkling of exciting phenomena waiting to be explored. 19 Gershtein's unpublished 1958 dissertation had sharpened the theoretical expectations of the enhancement of molecular-formation rates that Zel'dovich had suggested by predicting the (1, 1) excited state of the dlt molecular ion at less than 10 eV below threshold. E. A. Vesman, a student of Gershtein, made the idea concrete by pointing out the efficacy of the transfer of energy into vibrations of the electronic molecule for small energy releases.…”

A Personal Adventure in Muon-Catalyzed Fusion

Luis Alvarez and colleagues discovered muon-catalyzed fusion of hydrogen isotopes by chance in late 1956. On sabbatical leave at Princeton University during that year, I read the first public announcement of the discovery at the end of December in that wellknown scientific journal, The New York Times. A nuclear theorist by prior training, I was intrigued enough in the phenomenon to begin some calculations. I describe my work here, my interaction with Alvarez, and a summary of the surprising developments, both before and after Alvarez's discovery. The rare proton-deuteron (p-d) fusion events in Alvarez's liquid-hydrogen bubble chamber occurred only because of the natural presence of a tiny amount of deuterium (heavy hydrogen). Additionally, the fusion rate, once the proton-deuteron-muon (pdl -) molecular ion has been formed, is sufficiently slow that only rarely does an additional catalytic act occur. A far different situation occurs for muons stopping in pure deuterium or a deuterium-tritium (d-t) mixture where the fusion rates are many orders of magnitude larger and the molecular-formation rates are large compared to the muon's decay rate. The intricate interplay of atomic, molecular, and nuclear science, together with highly fortuitous accidents in the molecular dynamics and the hope of practical application, breathed life into a seeming curiosity. A small but vigorous worldwide community has explored these myriad phenomena in the past 50 years.
