New Article on Properties of Neutron Matter

The differences of charge radii of mirror nuclei – nuclei with exchanged numbers of protons and neutrons – provide information on the equation of state (EOS) of neutron matter. The differences of the recently measured charge radii of 36,38Ca and those of their stable mirror partner ³⁶S and ³⁸Ar allowed us to restrict a parameter of the EOS.
The result is consistent with earlier results including the recent detection of gravitational waves from the merger of two neutron stars.
