Boson Models with Interactions of Arbitrary Order
P. Van Isacker
The paper considers quantal many-boson systems that are described by a rotationally invariant and boson-number conserving Hamiltonian. The properties of a generic model are studied…

Relation between E2 transitions in even--even and odd-mass nuclei
P. Van Isacker
How is the B(E2;2_1^+ -> 0_1^+) value in an even-even nucleus related to corresponding B(E2;J_i -> J_f) values in a neighbouring odd-mass nucleus? If either neutrons or protons are…

Understanding Charge Radii with Machine Learning: Discovering Physics Expressions
B. Maheshwari, P. Van Isacker
We introduce a robust, interpretable machine learning (ML) framework that combines numerical regression for high-accuracy predictions with symbolic regression to uncover the underl…
