reactions. Their important role for nuclear reaction, nuclear structure and double beta-decay …

Two-proton emission and related phenomena

M Pfützner, I Mukha, SM Wang - Progress in Particle and Nuclear Physics, 2023 - Elsevier
One of characteristic phenomena for nuclei beyond the proton dripline is the simultaneous
emission of two protons (2p). The current status of our knowledge of this most recently …

Precise Spectroscopy of the and Systems via the and Reactions at Intermediate Energies

K Miki, K Kameya, D Sakai, R Urayama, N Imai… - Physical review …, 2024 - APS
To search for low-energy resonant structures in isospin T= 3/2 three-body systems, we have
performed the experiments H 3 (t, He 3) 3 n and He 3 (He 3, t) 3 p at intermediate energies …

Low Energy Structures in Nuclear Reactions with in the Final State

R Lazauskas, E Hiyama, J Carbonell - Physical Review Letters, 2023 - APS
We investigate a reaction model that describes a fast removal of the α particle from the He 8
nucleus with eventual emission of four neutrons. The obtained four neutron energy …

Volume extrapolation via eigenvector continuation

N Yapa, S König - Physical Review C, 2022 - APS
We develop an extension of eigenvector continuation (EC) that makes it possible to
extrapolate simulations of quantum systems in finite periodic boxes across large ranges of …

Three-body resonances in pionless effective field theory

S Dietz, HW Hammer, S König, A Schwenk - Physical Review C, 2022 - APS
We investigate the appearance of resonances in three-body systems using pionless
effective field theory at leading order with two complementary methods. The Faddeev …

Multi-body wave function of ground and low-lying excited states using unornamented deep neural networks

T Naito, H Naito, K Hashimoto - Physical Review Research, 2023 - APS
We propose a method to calculate wave functions and energies not only of the ground state
but also of low-lying excited states using a deep neural network and the unsupervised …

Low-Energy Dipole Strength in He

F Bonaiti, S Bacca - Few-Body Systems, 2024 - Springer
In this work, we present new ab initio coupled-cluster calculations of dipole-excited state
properties of 8 He based on the chiral effective field theory interaction 1.8/2.0 (EM). We focus …

Theory of halo nuclei

HW Hammer - Handbook of Nuclear Physics, 2022 - Springer
Halo nuclei are characterized by a few weakly bound halo nucleons and a more tightly
bound core. This separation of scales can be exploited in a few-body description of halo …

Searching for tetraneutron in bismuth nucleus photodisintegration reaction
