The rapid neutron capture process (r process) is believed to be responsible for about half of
the production of the elements heavier than iron and contributes to abundances of some …

In the last decade there has been a renaissance in laser spectroscopy at on-line facilities.
This has included the introduction of ion traps and the use of laser ion sources to study the …

Atomic physics techniques for the determination of ground-state properties of radioactive
isotopes are very sensitive and provide accurate masses, binding energies, Q-values …

A multi-task learning (MTL) framework, called gradient kernel ridge regression, for nuclear
masses and separation energies is developed by introducing gradient kernel functions to …

In this article a comprehensive description and performance of the double Penning-trap
setup JYFLTRAP will be detailed. The setup is designed for atomic mass measurements of …

The evolution of the ground-state nuclear shapes in neutron-rich Sr, Zr, and Mo isotopes,
including both even-even and odd-A nuclei, is studied within a self-consistent mean-field …

The kernel ridge regression (KRR) approach is extended to include the odd-even effects in
nuclear mass predictions by remodulating the kernel function without introducing new …

Penning trap measurements using mixed beams of 76Ge–76Se and 100Mo–100Ru have
been utilized to determine the double-beta decay Q-values of 76Ge and 100Mo with …

The radial basis function (RBF) and Bayesian neural network (BNN) approaches have been
widely used in nuclear mass predictions. In this work, the predictive powers of RBF and BNN …

Precision mass measurements of neutron-rich rhodium isotopes have been performed at the
JYFLTRAP Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line …
