[en] We point out that the deuteron wave functions of Certov, Mathelitsch, and Moravcsik contain a hidden assumption about the tensor potential at very short distances

[en] A group-theoretical method for the description of the giant dipole resonance in odd-mass nuclei is described and analytical expressions for the strength splitting are derived when nuclei exhibit axially symmetric deformation, corresponding to the SU(3)direct product U(2) limit of the interacting boson-fermion model

[en] Certain types of ring diagrams of the thermodynamic potential Ω can be summed up to all orders using two apparently very different methods---the eigenvalue method and the transition-amplitude method. A relatively simple derivation of these methods is given, and we show that these two methods are exactly equivalent to each other. To study their numerical applications we have calculated the particle-particle, hole-hole ring diagrams of Ω for nuclear matter with both methods, using a modified Gogny interaction. Our results suggest that the strength-parameter integration involved in the transition-amplitude method can be accurately performed using a small number of mesh points and both methods seem to be suitable for numerical calculations

[en] On the basis of perturbative quantum chromodynamics, we consider the bremsstrahlung energy losses of partons traversing parton matter using the well-known quantum electrodynamical formulas. We find the transport equation describing the energy distribution of partons as a function of thickness of a target. The equation is solved numerically and we briefly discuss the relevance of our results for hadron-nucleus and nucleus-nucleus collisions at high energies

[en] Convergence properties of the pseudostate method in the d+α system are investigated with respect to the number of deuteron Gaussian basis functions and the number of pseudo-inelastic configurations. Results indicate that the deuteron specific distortion effect can be well described by using about 10 to 15 Gaussian basis functions to generate deuteron wave functions in the ground and pseudo-excited states. Also, it is found that, for the ground-state energy of ⁶Li and for d+α scattering in the very low energy region, only deuteron pseudo-excited states with excitation energies less than about 60 MeV need to be included. In addition, the investigation shows that the calculated total reaction cross sections are rather severely underestimated, indicating that even more cluster configurations must be introduced into the resonating-group formulation in order to obtain a satisfactory explanation of all the important features of the six-nucleon system

[en] The composite spin observable tau/sub 22/equivalent(T/sub 22/+T/sub 20// √6 ) has been measured at five incident pion energies between 134 and 294 MeV, in an angular range between 90⁰ and 170⁰, using a tensor-polarized deuterium target. New, accurate data for the vector analyzing power iT/sub 11/ were obtained at the same time. In combination with the results reported in part I of this series, our measurements allow us to determine the three analyzing powers T/sub 20/, T/sub 21/, and T/sub 22/, separately, and compare them with existing theoretical calculations, all of which fail, in one way or another, to reproduce the entire data set

[en] The ⁹Be(t,α) reaction has been used to populate states in ⁸Li. Angular distributions were measured for four low-lying narrow states, and distorted-wave Born approximation calculations (including coupled channels) were used to analyze the data. The results are compared with results of a ⁹Be(d,³He) reaction and with Cohen-Kurath shell-model predictions
