Nuclear charge radius predictions by kernel ridge regression with odd-even effects
Lu Tang, Zhen-Hua Zhang
The extended kernel ridge regression (EKRR) method with odd-even effects was adopted to improve the description of the nuclear charge radius using five commonly used nuclear models…
Improved phenomenological nuclear charge radius formulae with kernel ridge regression
Jian-Qin Ma, Zhen-Hua Zhang
The kernel ridge regression (KRR) method with Gaussian kernel is used to improve the description of the nuclear charge radius by several phenomenological formulae. The widely used…
Possible antimagnetic rotation bands in Pd: a particle-number conserving investigation
Jian-Qin Ma, Zhen-Hua Zhang
The particle-number conserving method based on the cranked shell model is adopted to investigate the possible antimagnetic rotation bands in Pd. The experimental kinematic…
Systematic investigation of the high-spin structures in the odd-odd nuclei Re by a particle-number conserving method
Zhen-Hua Zhang, Shuo-Yi Liu
The recently observed two and four-quasiparticle high-spin rotational bands in the odd-odd nuclei Re are investigated using the cranked shell model with pair…
Rotational excitations in rare-earth nuclei: a comparative study within three cranking models with different mean fields and the treatments of pairing correlations
Zhen-Hua Zhang, Miao Huang, A. V. Afanasjev
High-spin rotational bands in rare-earth Er (), Tm () and Yb () isotopes are investigated by three different nuclear models. These are (i) the cranked relativisti…
Configuration and bandhead spin assignments for the 2-quasiparticle rotational bands in the neutron-rich nuclei Pm
Shuo-Yi Liu, Miao Huang, Zhen-Hua Zhang
The rotational bands in the neutron-rich nuclei Pm are investigated by a particle-number conserving method. The kinematic moments of inertia for the 1-quasiparticle ban…
