TL;DR: In this paper, the existence of a series of levels in three-particle systems has been investigated and it has been shown that the number of such levels may be very large.

TL;DR: In this paper, it was shown that the energy levels of an arbitrary anharmonic oscillator (x 2 m and in any finite number of dimensions) are determined uniquely by their Rayleigh-Schrodinger series via a generalized Borel summability method.

TL;DR: Hartree-Fock calculations have been made for closed shell nuclei using a form of density dependent nucleon-nucleon interaction suggested by Skyrme as discussed by the authors, which is very good for binding-energies, densities and energies of single particle levels near the Fermi level.

TL;DR: The assumption of statistical independence of matrix elements leads to ensembles of Hamiltonians which involve simultaneous interactions between many particles as discussed by the authors, and the resultant (semicircular) spectra are quite different from the Gaussian spectra found for Ensembles properly restricted to involve only two-body interactions.

TL;DR: In this paper, the effect of both the P3 and the P5 degrees of freedom on the potential energy surface of elements in the lead and actinide regions has been investigated.

TL;DR: In this article, the alpha-particle model of Margenau, Bloch and Bronk is used to study the ground-state properties, the relative energies of different alpha configurations and configuration mixing of light 4N nuclei from 12C to 28Si.

TL;DR: A 1.53±0.04 MeV proton activity with a 245±20 ms half-life has been observed in the reaction of 16O on 40Ca as discussed by the authors.

TL;DR: In this paper, the authors propose an alternative to the usual dual resonance model by considering charges and electrostatics on a sphere, and the four point Born term is shown to give the Virasoro model with a particular value of the intercept ( a = 2).

TL;DR: In this article, the authors discuss the possibility that diffraction scattering of hadrons conserves the s-channel helicities of the particles involved, and show that the available experimental data supports this hypothesis.

TL;DR: In this article, the angular distributions at q2 = 2.5 and 3.75 (GeV/c)2 are sufficient to provide values of the ratio GE/GM independent of the results from other laboratories.

TL;DR: In this article, the Veneziano formula with M closed loops was constructed by Nielsen's representation and by sewing reggeons, and the logarithm of its integrand is the third Abelian integral of a sphere with M handles.

TL;DR: In this paper, a Lorentz-invariant Lagrangian can be made conformally invariant provided a gauge field φ μ is introduced as part of a covariant derivative.

TL;DR: In this paper, the precompound emission probability is derived using the transition rates developed and the properties of the result are discussed, and the restriction on transitions among the intermediate particle-hole states due to the two body nature of the residual interaction is examined.

TL;DR: In this article, it was shown that failure to detect positron-proton coincidences in the decay of this isomer establishes its direct proton radioactivity, with a threshold of 26.3±0.4 MeV which can only arise from 53Com.

TL;DR: In this paper, it was shown that the limit of sums of very high order, unrenormalized planar Feynman diagrams lead to dual N point functions, and the parton mass turns out to be of the order of one GeV.

TL;DR: In this article, a phase shift analysis is made from the π − π o and π + π− elastic scattering data obtained through Chew-Low extrapolation with high statistics of the ρ − p→ π O p and ρ O p → π+ π n reactions at 2.77 GeV/c.

TL;DR: In this article, a Veneziano formula for external reggeons is presented, which transforms neatly under twists, gauges, propagation and factorizatio. And it suggests a third quantized field theory.

TL;DR: In this article, experimental results for the polarization parameter P0 in π ± p, K ± p, pp, and p p elastic scattering at 6 GeV/c, and in the range of the invariant four-momentum transfer squared −t from 0.05 to ∼ 2.2, were presented.

TL;DR: In this paper, it was shown that each muonic X-ray determines the value of a certain function averaged over the nuclear charge distribution, which is not well represented by a single fractional power rk as suggested by Ford and Wills.

TL;DR: In this article, a 65 s, α-particle emitting isotope of element 104, rutherfordium, by bombarding 248Cm with 18O ions, was identified based on milking the 26 s daughter, 257No.

TL;DR: In this article, all available data (11 cases) on mirror beta-decay are analyzed and the results scatter widely but the mean trend of (∫t) + ( ∫) − − 1 is significantly positive, consistent with a linear dependence on W+o+W−o and, without correction, would correspond to gIT≈ 2 × 10−3 (with gV=1) for the strength of the induced tensor coupling.

TL;DR: In this article, a method for the treatment of single-particle resonances in the theory of nucleon-nucleus scattering is introduced which finds application in the projection operator theory of Feshbach.

TL;DR: The emitters of isomeric X- and γ-rays (t 1 2 = 0.1 − 100 μ s ) among primary fission products in 235 U-thermal neutron fission have been identified.

TL;DR: In this article, the relativistic and radiative corrections to the magnetic moment of a hydrogen atom were considered with the account of effects of the recoil of the bound system as a whole.

TL;DR: In this article, the correction due to exchange currents to the one-body 3 H → 3 He β-decay amplitude was estimated, treating the D-state part of the wave function in a simple approximate way.

TL;DR: In this article, the decay amplitude ϵ o = 2 3 η +− + 1 3η oo is decomposed into a CPT-conserving, T-violating part ϵ, and a T-Conserving, CPT violating part δ, using the measurement of the phase of ηoo together with other results on Ko decays.

TL;DR: In this article, a new hypothetical interaction between neutrinos is considered, and it is shown that even relatively strong ν e − ν, ν μ - ν ε and ν µ − ε interactions are not in contradiction with existing data and upper limits for the corresponding interaction constant are obtained.

TL;DR: In this article, the observed large quadrupole moment of the collective 3 − state in 208 Pb was found to imply a considerable splitting of the two-octupole-phonon quarter.

TL;DR: In this article, the α-particle by inelastic electron scattering was studied at momentum transfers and the assignment 0 + for the state at 20.10 ± 0.05 MeV (measured excitation energy) has been definitely established.
