Direct demonstration of the completeness of the eigenstates of the Schrodinger equation with local and non-local potentials bearing a Coulomb tail
Nicolas Michel
Demonstrating the completeness of wave functions solutions of the radial Schrodinger equation is a very difficult task. Existing proofs, relying on operator theory, are often very…
A New Efficient Method of Hartree-Fock-Bogoliubov Calculation for Weakly Bound Nuclei
M. Stoitsov, N. Michel, K. Matsuyanagi
We propose a new method to solve the Hartree-Fock-Bogoliubov equations for weakly bound nuclei, which works for both spherical and axially deformed cases. In this approach, the qua…
Fast computation of the Gauss hypergeometric function with all its parameters complex with application to the Poschl-Teller-Ginocchio potential wave functions
N. Michel, M. V. Stoitsov
The fast computation of the Gauss hypergeometric function 2F1 with all its parameters complex is a difficult task. Although the 2F1 function verifies numerous analytical properties…
Threshold Effects in Multi-channel Coupling and Spectroscopic Factors in Exotic Nuclei
N. Michel, W. Nazarewicz, M. Ploszajczak
In the threshold region, the cross section and the associated overlap integral obey the Wigner threshold law that results in the Wigner-cusp phenomenon. Due to flux conservation, a…
Precise Coulomb wave functions for a wide range of complex l, eta and z
N. Michel
A new algorithm to calculate Coulomb wave functions with all of its arguments complex is proposed. For that purpose, standard methods such as continued fractions and power/asymptot…
Shell Structure of Exotic Nuclei
J. Dobaczewski, N. Michel, W. Nazarewicz +2
Theoretical predictions and experimental discoveries for neutron-rich, short-lived nuclei far from stability indicate that the familiar concept of nucleonic shell structure should…
