On the complete basis of Pauli-allowed states of three-cluster systems in the Fock-Bargmann space. (English) Zbl 0884.47050
Summary: In the Fock-Bargmann space, the complete harmonic-oscillator basis for the three-cluster system is constructed. The indices of the reduction \(U(6)\supset U(2)\times U(3)\) are chosen as the quantum numbers. The Pauli-forbidden states are eliminated by the orthogonal transformation of basis functions. The basis states are obtained in terms of hypergeometric functions and the spherical Wigner functions. Their simple form allows one to solve the problem of calculating the matrix elements of the microscopic Hamiltonian needed for the study of three-cluster systems within the algebraic version of RGM.
