Some theoretical models postulated that, in addition to neutrons, such stars also would contain certain other exotic subatomic particles called hyperons or condensates of kaons: these results rule out those ideas.
240] produces too many "early" neutrons to allow the nuclear explosion to take place on the rigid timetable it must follow to become an effective bomb.
These facilities demonstrate the growth in the field of fundamental neutron physics and present additional opportunities for experiments requiring large densities of ultracold neutrons, exploiting higher fluences of pulsed cold neutrons, or training future generations of neutron scientists.
If the gap between the access tube and the soil is filled with air, neutron loss in the air results in neutron counts being underestimated, whereas if the gap is filled with water, more neutrons find their way back to the detector, and the neutron count is overestimated.
The proposed Canadian Neutron Facility (CNF) will be centred on a new medium-flux nuclear reactor as the source of neutrons for experiments performed both inside and outside the reactor core.
Varian will market the LANSAR line from AccSys Technology for non-destructive testing applications, including neutron radiography, nuclear waste assay and on-line mineral analysis.
