We report on a semi-analytical model for studying the evolution of the spin period P of a magnetic neutron star as a function of the baryonic mass load M[sub acc]. We have taken into account different equations of state and included rotational deformation effects. The presence of a strong gravitational field has also been considered in the context of general relativity. A comparison with numerical fully relativistic codes shows that our description is accurate within 5%. © 2000 American Institute of Physics.

    Larmor precession has been used in the past in neutron spin-echo and neutron depolarisation. In the last decade, interest has been revived in the inclined front and end faces of the precession regions combined with the neutron-resonance spin-echo (NRSE) technique. Various techniques based on...

    The performance of the coils used for a resonance spin-echo spectrometer is simulated to obtain the optimum parameters. The possibility to use a round wire instead of a flat band for coil production is explored. The parameters of the static bootstrap coils were varied in a 2D approach and a...
