Study Reveals Enhanced Triple-α Reaction Reduces Nucleosynthesis in Supernovae

In a recent study published in Nature, scientists reveal that the enhanced triple alpha reaction in the high temperature and high density environment increases the production of 12C, which reduces the robustness of proton-rich nucleosynthesis in supernovae. Their findings change a long-standing view on the origin of Mo and Ru isotopes.In a recent study published in Nature, scientists reveal that the enhanced triple-alpha reaction in the high temperature and high density environment increases the production of 12C, which reduces ...

Scientists reveal reaction mechanism of ¹¹Be nucleus

For the first time, researchers at IMP and their collaborators have studied the elastic scattering and breakup reactions of 11Be on 208Pb at an incident energy of 140 MeV, which corresponds to about 3.5 times of the Coulomb barrier (VB≈39.5 MeV). The experiment was conducted at the Radioactive Ion Beam Line in Lanzhou, the Heavy Ion Research Facility of Lanzhou (HIRFL-RIBLL). Scientists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators have lately made new progress in the study of the reaction mechanism of 11Be n...

Researchers Present New Measurement of Deuteron Collective Flow at RHIC-STAR

Relativistic heavy ion collisions can form a new strongly interacting matter — Quark Gluon Plasma (QGP), which is believed to be the state of our universe in the early moments of the big bang and the state of the inner neutron stars. Recently, researchers at the Institute of Modern Physics measured one of the deuteron collective flow, directed flow (v1), in Au+Au collisions at energies of 7.7-...Relativistic heavy ion collisions can form a new strongly interacting matter — Quark Gluon Plasma (QGP), which is believed to be the state of our universe in the early moments of the big bang and ...

Scientists Discover the Largest Isospin Asymmetry in Nuclear Low-lying States

In a recent study published in Physical Review Letters, researchers at the University of Hong Kong (HKU), the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators studied β-delayed one-proton emissions of 22Si, and discovered the largest isospin asymmetry in nuclear low-lying states. Symmetry exists extensively in nature. Examples range across size scales from macroscopic objects, such as spiderwebs or honeycombs, to the microscopic world with its arrangement of atoms in molecu...

Researchers Develop First Angular Momentum Conserved Transport Model for Ultra-relativistic Many-body Systems

Dr. LIU Shuai at Quark Matter Research Center, Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, together with researchers at Texas A&M University and Laboratori Nazionali del Sud, have developed the first angular momentum conserved transport model for ultra-relativistic many-body systems and applied it to study the spin physics in heavy-ion collisions. Transport model is an important theoretical tool used in non-equilibrium many-body systems to describe the evolution of particles’ microscopic states such as momentum, position and spin. Boltzmann...
