  By using a highly accurate variational wave function with 50 parameters for hydrogen molecule^[4] and the wave function of HeH⁺ used by Wolniewicz with 64 parameters^[5], the behavior of the β-spectrum of H-T→ HeH⁺+β^-+νe is discussed. The spectral shape thus obtained deviates remarkably from the β-spectrum of an atomic triton, and hence is different from the for mula used by Lyubimov et al. in determining the neutrino mass. This means that the "atomic approximation" is invalid in describing the molecular β-spectrum of valine, and the conclusion about the value of neutrino mass based upon the analysis of β -spectrum of valine also cannot be regarded as a reliable one. Therefore, in order to obtain ari accurate value of neutrino mass from the β-spectral shape, it is important to investigate the structure of the radioactive source, from which the corection has arisen.

  The periodic s-d model is investigated by Green's function methods. A closed set of equations for Green's function of Kondo-lattice system and a formula of single electron self-energy are obtained in the presence of a broken rotational symmetry. The formula can-be used to discuss low temperature anomalous properties of Kondo-lattice system with spontaneous magnetization or in an external magnetic field. We have evaluated the influence of magnetic ordering on logarithmic sin-gularity of electron self-energy by perturbative method to Leading logarithmic order (LLO).The result obtained indiGates there exists a competition between Kondo effect and Zong range magnetic ordering. The static susceptibility in the paramagnetic case has been evaluated, too.

  A theoretical scheme using closed time-path Green's functions is proposed to describe the quantum statistical properties of the order parameter in terms of.a generating functional.The dynamic ewlutionj,s generated by a driving source, while the statistical correlation by a fluctuation source, The statistical causality is shown to hold explicitly and to give rise to a number of important consequences. The pmbletn of determining the quantum statistical properties for the,order parameter is reduced to finding a solution of the functional equation for it.

  ON THEORY OF THE STATISTICAL GENERATING FUNCTIONAL FOR THE ORDER PARAMETER(II) —DENSITY MATRIX AND THE FIELD-THEORETICAL STRUCTURE OF THE GENERATING FUNCTIONAL

  Several equivalent,expressions for the generating functional of the order parameter are derived in this paper to elucidate how the statistical properties are incorporated in its field-theoretical structure. It is shown that in the process of determining the generating functional the dynamic evolution and the statistical information can be separated to a certain extent which facilitates solving the problem. The whole procedure is greatly simplified if the statistical correlation is Gaussian or a generalized fluctuation-dissipation theorem (FDT) holds. As an example, the Gaussian character of the thermal-equilibrium distribution is justified and the Matsubara technique.along the imaginary time axis is extended to the real axis to provide a complete perturbation scheme for the closed time-path Green's functions (CTPGF).

  A generalized theory of ³He-A phase superfIuid is estab- lisped, which can comprise the Khalatnikov-Lebedev's theory treated as a special case, The starting point of this work is the Zilsel's principle in which the density of the super- fluid component is defined as an independent variable, It has the advantage of including naturally the "healing effect" of ³He-A superfluid liquid, whereby overcoming the difficulties encountered in Khalatnikov-Lebedev's theory.

  In this paper we first present the gauge invariant conserved Noether current for the Yang-Mi11s theory, which is nonlocal is some sense. Then we introduce for the two dimensional chiral model, plain and supersymmetric, the nonlocal one-complex parameter-dependent symmetric generators, which shift the Lagrangian density by a total divergence. Both the equations of motion and the energy momentum density are tnvaunt. The associated ically Into infinite Noether current may be expanded analyt-series of nonlocal currents.

  The independent particle approximation is used to treat the bound state problems in the quark model. The solution for meson states obtained in this approximation is the same as that obtained from the Bethe-Salpeter equation. The solution for the baryon states is also obtained. The mass spectra of mesons and baryons determined from these equations are in agreement with the experiment.

  In this work, the analysis of the space-time manifolds, their kinematic groups and Lie algebras are made as intuitive as possible. First of all, an analysis ofthe inertial frames shows that the space-time manifold in which there exists a global inertial frame should be a pseudo-sphere so that the kinematic group must be a rotation group. Thus the explicit analytical expressions of such kinematical transformations and the commutation relations among the corresponding generators can be formulated easily. Consequently, the contractions of such manifolds,kinematic groups and Lie algebras can be deduced concretely and intuitively.

  The infrared behavior of the running coupling constant in QCD has been studied using the Schwinger-Dyson equation of the gluon propagator based on the Slavnov-Taylor identities in axial gauge. It is shown that the infrared running coupling constant behavior g^-2(Q²)=g²(μ²/Q²) in the infrared limit Q²/μ²→0.
