Colour-singlet clusters in systems composed of six quarks
S. Mickevicius, G. P. Kamuntavicius
We present an investigation of six quarks system kinematics, independent on quark-quark interactions. There has been created and investigated basis of six quarks antisymmetrical an…
Elimination of Spurious States of Oscillator Shell Model
A. Deveikis, G. Kamuntavicius
A new method for elimination of the 'spurious' states comprising reguirement of translational invariance and simplicity of the enumeration scheme of antisymmetric A-particle states…
Intrinsic Density Matrices of the Nuclear Shell Model
A. Deveikis, G. Kamuntavicius
A new method for calculation of shell model intrinsic density matrices, defined as two-particle density matrices integrated over the centre-of-mass position vector of two last part…
Coefficients of Fractional Parentage for Nuclear Shell Model
A. Deveikis, G. Kamuntavicius
A new procedure for the calculation of shell model coefficients of fractional parentage has been developed. This procedure is free of numerical diagonalization, orthogonalization,…
