TL;DR: In this article, the γ-ray spectrum accompanying the p p annihilation at rest has been measured with a large NaI(Tl) spectrometer with a confidence level of 99.0, 97.5%, and 98.2%.

TL;DR: In this article, the high-energy part of the spectrum was used to deduce branching ratios for the so far unobserved annihilation channels: R(p p →π 0 ω) = (2.38 ± 0.65)%, R( p p → π 0 η ) = (0.82 ± 0.04)% and an upper limit for the π0η′ channel was deduced.

TL;DR: In this paper, a high-precision measurement of the finest structure splitting in the circular 11→10 X-ray transition of the Pb was performed and the experimental value of 1199(5) eV was in agreement with QED calculations.
Abstract: A high-precision measurement of the finestructure splitting in the circular 11→10 X-ray transition of\(\bar p^{208} Pb\) was performed. The experimental value of 1199(5) eV is in agreement with QED calculations. From that value the magnetic moment of the antiproton was deduced to be −2.8005(90)μnucl. With this result the uncertainty of the previous world average value was reduced by a factor of ≈2. A comparison with the corresponding quantity of the proton now yields:\({{\left( {\mu _p - \left| {\left\langle {\mu _{\bar p} } \right\rangle } \right|} \right)} \mathord{\left/ {\vphantom {{\left( {\mu _p - \left| {\left\langle {\mu _{\bar p} } \right\rangle } \right|} \right)} {\mu _p }}} \right. \kern-

TL;DR: The γ-ray spectrum after p annihilation at rest was measured in two independent high-statistics runs as discussed by the authors, showing narrow peaks corresponding to masses of 1210, 1638, 1694 and 1771 MeV.

TL;DR: The strong interaction effects in antiprotonic 16O, 17O, and 18O atoms were measured at the CERN LEAR facility, where the shifts ϵ and the widths Γ of the 3D level were determined to be −112±20 eV ( 16 O ), −140±46 eV( 17 O ), −195±20eV ( 18 O ) and 495±45 eV

TL;DR: The purpose of this chapter is to review this “traditional” approach in the area of nuclear forces and their applications to nuclear structure.
Abstract: Nowadays it has become customary in nuclear physics to denote by “tradition” the approach that considers nucleons and mesons as the relevant degrees of freedom. It is the purpose of this chapter to review this “traditional” approach in the area of nuclear forces and their applications to nuclear structure.

TL;DR: In this article, it was shown that the meson σ and κ mesons exhibit a spectrum of (squared) masses which are proportional to the sum of orbital angular momentum and radial quantum numbers.

TL;DR: This version of A = 16 diers from the published version is slightly revised in that it has corrected some errors discovered after the article went to press and Reference key numbers have been changed to the NNDC/TUNL format.
387 citations
TL;DR: In this paper, the energy levels of the A = 18 and 19 nuclei were compared, with an emphasis on the review of material leading to information about the structure of the two nuclei.

TL;DR: This paper investigates {ital q{bar q}} meson decay amplitudes assuming pair production from the scalar confining interaction and from one gluon exchange and finds the OGE decay amplitude to be subdominant in most cases.
Abstract: In this contribution the author discusses models of two-body strong hadron decays. These models are expected to play a vital role in future attempts to identify unconventional hadrons such as glueballs and hybrids, through accurate predictions of the decay modes of conventional q{anti q} states. First, he reviews the most commonly used decay model, which is the {sup 3}P{sub 0} model developed by Micu and LeYaouanc et al., and show some of its successful predictions. Predictions of the {sup 3}P{sub 0} model for some newly discovered states are also given. Finally he discusses some attempts to identify the fundamental QCD process which underlies q{anti q} pair production in the {sup 3}P{sub 0} model. His results indicate that the dominant q{anti q} pair production process is usually pair production through the linear scalar confining interaction. Pair production from OGE in most cases is found to be a smaller amplitude, with the notable exception of {sup 3}P{sub 0} {yields} {sup 1}S{sub 0} decays such as f{sub 0}(q{anti q}) {yields} {pi}{pi}.
