IONIZATION OF THE HYDROGEN NEGATIVE ION IN A UNIFORM ELECTRIC FIELD

The ionized Lifetime of the hydrogen negativeion in a uniform electric field is again calculated by using improved perturbation theory.The choice of the H^--ion wave function and the normalization of wave function of continuous state are discussed. The numerical calculations by using Rotenberg-Stein wave function with five parameters are performed. Comparison of our results with experimental results obtained by G. M. Stinson et al. is given.     

THE MIXEFIFNECTG OF Z0 AND TOPONIUN

It is shown that the mixing effect between the Z⁰ and the toponium will significantly affect various properties of toponium state.     

IS THE NEUTRINO MASS EQUAL TO 34 eV?--A DISCUSSION OF THE ATOMIC EFFECT IN THE β-DECAY OF H3

In evaluating the β-spectrum of atomic H³ a more accurate formula is obtained. in which the first three transitions leading to the Lowest three states of ³He⁺ are treated exactly, and the cJosure approximation is used to estimate the contribution from all excited states with n>3.The formula obtained is compared with what is used by Lyubimov et al.^[1] in determining the neutri-no mass. As a result it has been shown that the formula used by Lyubimov et al. does not yield an adequate accuracy. Especially the end-point energy they obtained may differ from the true value by 13.6 ev, which would cause an uncertainty of the same order inthe value of the neutrino mass.     

COMPOSITE FIELD THEORY AND THE STRATON MODEL(Ⅱ)

On the basis of previous papers,this work discusses the theory of composite fields composed of colored stratons.Varicus equivalent representations of the S-matrix elements are given.The formulae for the transition matrix elements between states involving baryons in the theory of Straton Model are derived.Finally,the field- current relations are extended to spin 1/2 baryons and their applications are discussed.     

THE PERTURBATION EXPANSION OF THE QUANTIZED COMPOSITE FIELD THEORY AND GAUGE INVARIANCE

In this paper we introduce the concept of "same order" in the perturbution expansion of the quatized composite field theory which is different from single particle theory. For example, in the case of Q. E. D., "same order" is defined by means of a coupling constant, but here it closely relates the operators occuring in the B. S. equations. Feymann graphs of the "same order" are defined for different kinds of transitions in the composite field theory. Finally, we prove that guage invariance is a natural result as long as all "same order" Feymann graphs are calculated for an electromagnetic transition between composite particles.
