The Meson Theory of Nuclear Forces I. General Theory

In this paper, the meson theory of nuclear forces is presented in a simplified way, As in Yukawa's first paper, the forces between two nuclear particles are derived directly from the field equations and the Hamiltonian of the meson field ($2,3), without quantization of the field. The charge dependence of the forces is discussed (f4) and it is found that only two assumptions are in agreement wit...

Correlations and Pairing in Nuclear

The innuence of correlations on the critical temperature and density for the onset of superruidity in nuclear matter is investigated within the scheme of Nozi eres and Schmitt-Rink 1]. For symmetric nuclear matter a smooth transition from Bose-Einstein condensation (BEC) of deuteron-like bound states at low densities and low temperatures to Bardeen-Cooper-Schrieeer (BCS) pair-ing at higher dens...

The Meson Theory of Nuclear Forces. Part II. Theory of the Deuteron

With the nuclear forces as derived in the first part of this paper the deuteron problem is integrated. In $7, natural units are introduced, vis. , the range of the nuclear forces 1/K=A/pc as the unit of length and the quantity Eo=p~c2/M as the unit of energy. With the adopted value of the meson mass, p=177 electron masses, we have 1/K =2.18&)(10 cm and Z0= 8.68 Mev. The quantum states to be exp...

Pairing correlations and transitions in nuclear systems

We discuss several pairing-related phenomena in nuclear systems, ranging from superfluidity in neutron stars to the gradual breaking of pairs in finite nuclei. We describe recent experimental evidence that points to a relation between pairing and phase transitions (or transformations) in finite nuclear systems. A simple pairing interaction model is used in order to study and classify an eventua...

Off-centre instability induced by exchange forces

Theory of the off-centre instability is developed for the impurity ions (Li', CuC, and Ag') in alkali halides on the basis of the charge transfer excitation model which is different in the involved electronic processes from the earlier theory based on the polarizable-point charge ion model. The lowest potential minima for the impurity ion along < 11 1 ), ( 110 ), and < 100 ) crystal axes are ca...
