In the 1970s, the merger of a neutron star and a black hole was suggested as a potential candidate. This scenario has been also investigated in detail, especially in recent years in combination with gravitational wave detection. Our understanding today is that the r-process occurs in neutron ...
The oscillation of neutronninto mirror neutron, its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter. In quark starstransitions are suppressed. We study the structure of mixed stars and derive t...
To model the magnetic domain scattering on a non-polarised instrument, an evenly weighted linear combination of the down- and up-spin reflectivity contributions was used. This approach assumes the size of the magnetic domains in the iron and iron oxide layers are larger than the neutron coherence...
Heavy atomic nuclei have an excess of neutrons over protons, which leads to the formation of a neutron skin whose thickness is sensitive to details of the nuclear force. This links atomic nuclei to properties of neutron stars, thereby relating objects that differ in size by orders of magnitude....
Accurate neutron powder diffraction experiments at several temperatures allow one to monitor the reconstructive tetragonal to monoclinic phase transition as a function of the size of zirconia nanoparticles. The structure of the tetragonal phase observed in the nanocrystals is identical to that observed in...

Self-powered (s-p) detectors are useful for incore neutron measurements in nuclear reactors because of their small size, ruggedness and simplicity. In one type of detector, a delayed current results from the beta activity induced in the device by the neutron flux while a second type gives an...
B. Jimmy Neutron This is a funny, silly, and colorfully animated children’s film featuring Jimmy Neutron. Jimmy has created all kinds of interesting things to make his life easier, including a robotic dog, Goddard, who follows him everywhere. Jimmy and his friend, Carl, use a homemade sp...
Here we describe the Lunar Lander Neutron & Dosimetry experiment (LND) which is part of the Chang’E 4 Lander scientific payload. Its chief scientific goal is to obtain first active dosimetric measurements on the surface of the Moon. LND also provides observations of fast neutrons which are a...
