Enhancement of alpha-decay by positive hexadecapole deformation
Kai Ren, Minghui Hu, Pengfei Ma +2
Whether hexadecapole deformation () influences decay remains controversial: machine-learning analyses suggest a strong link to cluster preformation, while empirical formul…

Extracting nuclear charge radii from binding energies: a single-parameter empirical formula with structural corrections
Pengfei Ma, Minghui Hu, Kai Ren +2
Nuclear binding energies and charge radii stem from the same underlying physics: saturation, isospin dependence, shell structure, and deformation. Binding-energy data therefore pro…

Analytical penetration probability including the centrifugal potential: An improved Buck--Merchant--Perez model for alpha-decay half-lives
Minghui Hu, Pengfei Ma, Kai Ren +2
We derive a closed-form, non-perturbative WKB penetration formula for alpha-decay that explicitly incorporates the centrifugal potential within the Buck--Merchant--Perez (BMP) clus…
