From masses and radii of neutron stars to EOS of nuclear matter through neural network
The equation of state (EOS) of dense nuclear matter is a key factor to determine the internal structure and properties of neutron stars. However, the EOS of high-density nuclear matter has great…

Interference of resonances in two-proton emission of 16Ne
We investigate the two-proton (2p) emission from 16Ne with the time-dependent 14O+p+p three-body calculations. Two 0+ resonances are suggested to participate. For the 0+1…
