In this paper, the three-body bound state collapse (BSC) is investigated in connection with the short-range orthogonality node by making use of the unitary pole approximation of a deep local 2N potential model. A rank-1 effective $^{3}$${\mathit{S}}_

The two- and three-cluster fish bone optical model with hard core correlations is derived from the corresponding resonating group model. The nuclear saturation effect is represented by three different features of inter-cluster interactions:i) by the

Using the HFDHE2 He-He potential of Aziz et al. (J. Chem. Phys. 90, 4330 (1979)) with the Faddeev-Yakubovsky theory, we have calculated the /sup 4/He atom-triatom scattering length and found it to be -116 A. We reduced the s-wave two-body t matrix to

The influence of hard core correlations on the effective interactions in theΛ-α andΛ-Λ-α systems is studied. It is found that the hard core correlations modify the shape of the effectiveΛ-α potential such that the minimum is no longer at the o

Significant underbinding for the triton of a quantum-chromodynamically motivated realistic NN potential containing a superdeep short-ranged attraction and a forbidden state in the S-italic waves has been reported from a previous Faddeev calculation.

A microscopically substantiated αα potential model is proposed. In contrast to the conventional resonating group method spanning a restricted allowed space, the new potential operates in the complete relative motion space. The inclusion of the so-c

Matrix elements of the three-body Pauli potential are calculated in thenpα resonating group model. They are small (~1%) compared with matrix elements of the two-body subsystem potentials, provided that correct normalization of all relative motion so

A variational calculation is performed for the (3He)4 system interacting pairwise through the Lennard‐Jones He–He potential. Use of an integrodifferential Euler equation is made to determine an optimum wave function, leading to results showing th

The distortion of composite particles (clusters) during their mutual interaction leads to effective three-body forces. In a nonrelativistic theory, they originate from two sources. One is the coupling potential which couples a channel to a distortion

The binding energy of 3He(4He)2 is recalculated with more correct ℏ2/M values. The Smith‐Thakkar, HFDHE2, and mDD‐2 potentials ensure its binding, while the Beck, Lennard‐Jones, and ESMMSV potentials do not.
