Description

Accreting neutron stars are expected to emit a redshifted 2.2 MeV line resulting from neutron capture. The detection of this line would provide constraints on the neutron star equation of state and offer insights into the nuclear reactions within the neutron star atmosphere. We have developed a theoretical framework aimed at predicting the optimal X-ray luminosity for the detection of this line in strongly magnetized neutron stars. The results from analyzing INTEGRAL/SPI data of a representative sample of accreting neutron stars are presented. Additionally, the prospects for future MeV missions are explored.
