We analyze observations of eight quiescent low-mass X-ray binaries in globular clusters and combine them to determine the neutron star mass-radius curve and the equation of state of dense matter. We determine the effect that several uncertainties may have on our results, including uncertainties in the distance, the atmosphere composition, the neutron star maximum mass, the neutron star mass dis...

This paper demonstrates the feasibility of creating specific defects in double-heterostructure InGaN/GaN commercial light-emitting diodes by neutron irradiation. Using controlled neutron energy, only one failure mechanism can be activated. Defects are located on the side of the chip and increase the leakage current driven by the well-known Poole–Frenkel effect with Ec − ET = 130 meV electron tr...

The idea that gamma-ray bursts might be a kind of phenomena associated with neutron star kicks was first proposed by Dar & Plaga (1999). Here we study this mechanism in more detail and point out that the neutron star should be a high speed one (with proper motion larger than ∼ 1000 km/s). It is shown that the model agrees well with observations in many aspects, such as the energetics, the event...

Introduction: One of the concerns about using of high energy photons in radiotherapy is neutron contamination production. The threshold energy of photoneutron production in most materials with high atomic number is about 7MeV. Therefore, it seems to be logical that the main components with high atomic number elements used in the LINAC head have a large contribution to the neutr...

The possibility of a gravitational phase transition, especially with respect to neutron stars is investigated. First, a semiclassical treatment is given, predicting a gravitational London penetration depth of 12km for neutron stars. Second, the problem is considered from a GinzburgLandau point of view. A gravitational Meissner effect, a gravitational Aharanov-Bohm type effect and a gravitationa...

We describe the (p, n) quasi-elastic scattering taking into account the contributions coming from those parts of the neutron-proton density difference that arise from the Coulomb distortion of the nuclear densities and from the polarizing effect of the excess neutrons on the self-conjugate core. The model proposed is a generalization of the Lane model and of the folding model of the interaction...

Thermal surface emissions have now been detected from more than a dozen isolated neutron stars, including radio pulsars, radioquiet neutron stars and magnetars. These detections can potentially provide important information on the interior physics, magnetic fields, and surface composition of neutron stars. Understanding the properties of matter and radiative transfer in strong magnetic fields i...

The structure and decay of 26O are investigated in a three-body 24O+n+n model suitable for studies of the long-lived (including radioactivity time scale) states. We have found extremely strong effects of the subbarrier configuration mixing on the decay width of true 2n emitters due to core recoil and neutron-neutron final state interaction. This effect far exceeds the analogous effect in the tr...
