Neutron decay spectroscopy of neutron-rich oxygen isotopes has been performed using the two-proton knock-out reaction 9Be(26Ne,X)24,23,22O. A combination of the knock-out of valence and core protons can explain the three observed spectra. These knock-out processes are selective and preferentially populate hole states. The observed narrow resonance state in 23O at an excitation energy of 2.8(1) ...
I describe work on two aspects of magnetic field evolution relevant for the “recycling” scenario for making millisecond radio pulsars. First, many of the theoretical ideas for bringing about accretion-induced field decay rely on dissipation of currents in the neutron star crust. I discuss field evolution in the crust due to the Hall effect, and outline when it dominates Ohmic decay. This emphas...
In many nuclear reactions, one or more excited primary fragments are formed which decay by the evaporation of nucleons and light clusters. This evaporation process can substantially alter the proton-neutron asymmetry of the initial primary fragments. In a study of complex fragment emission in fusion reactions, the Z values of the detected secondary fragments were measured @1#. In order to estim...
Context. In the magneto-centrifugal mechanism for jet formation, accreting neutron stars are assumed to produce relativistic jets only if their surface magnetic field is weak enough (B ∼ 108 G). However, the most common manifestation of neutron stars are pulsars, whose magnetic field distribution peaks at B ∼ 10 G. If the neutron star magnetic field has at least this strength at birth, it must ...
