Spectroscopic amplitudes in microscopic three-cluster systems [PDF]
Physical Review C, 2023 I investigate three-body spectroscopic amplitudes in a microscopic three-cluster model. The total wave functions are described in the resonating group method (RGM) formalism based on cluster wave functions and on relative functions defined in the hyperspherical method. Core excitations are included.

Alpha-particle spectroscopic amplitudes and the su(3) model
Nuclear Physics A, 1973 Abstract Formulas for calculating spectroscopic amplitudes for emission or transfer of α-particles are developed in the framework of the harmonic-oscillator shell model with SU(3) classification. These formulas are applied to some interesting states of 20Ne, e.g., low-lying (sd)4 shell-model states, members of the lowest K = 0− band with SU (3) label

Spectroscopic amplitudes for α-clustering in 6Li and 7Be
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1984 Abstract Spectroscopic amplitudes for α -clustering in the bound states of 6 Li and 7 Be are computed by adopting the definition of Fliessbach. The wavefunctions used are those from coupled-channel resonating-group calculations. Using these amplitudes, one can determine the spectroscopic factor and the constant characterizing the asymptotic ...

Spectroscopic amplitudes and microscopic substructure effects in nucleon capture reactions [PDF]
Physical Review C, 2001 Spectroscopic amplitudes play an important role in nuclear capture reactions. These amplitudes are shown to include both single-particle and polarization effects: the former through their spatial dependence and the latter through their normalization (the spectroscopic factors).

Calculation of spectroscopic amplitudes using boson expansion wave functions [PDF]
Nuclear Physics A, 1975 Abstract A formalism is derived which allows the evaluation of spectroscopic amplitudes for two-nucleon transfer reactions. The transfer is assumed to take place between low-lying collective states described by boson expansion wave functions. Numerical calculations have been performed for (t, p) reactions on148, 150, 152Sm.

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2019 We present the first experimental determination on the spectroscopic amplitudes (SAs) for the α-cluster in the B11 ground state via the Li7(Li6,d)11B reaction using a high-precision magnetic spectrograph.

Spectroscopic amplitudes for complex cluster systems [PDF]
Nuclear Physics A, 1981 Abstract By expanding the Bargmann-Segal integral transform of nomi and overlap kernels in appropriately SU(3) coupled Bargmann space functions, the calculation of norm and overlap matrix elements in a cluster model basis is reduced to purely algebraic techniques involving the algebra of SU(3) recoupling transformations.
