Abstract
The magnetic susceptibility of a neutron gas at zero temperature, an idealization of neutron-star matter, is estimated for the realistic, soft-core nucleon-nucleon potential of Reid. For mass densities below twice that of ordinary nuclear matter, there is no sign of a ferromagnetically favorable instability of the normal ground state of the system, the effect of the interactions being to depress the magnetic susceptibility relative to its Fermi-gas value.
