In order to improve on current prompt fission neutron spectrum measurements, a gamma multiplicity tagging method was developed at the Rensselaer Polytechnic Institute Gearttner Linear Accelerator Center. This method involves using a coincidence requirement on an array of BaF2 gamma detectors to determine the timing of a fission event. This allows for much larger fission samples to be used due t...
The formation of a di-nuclear system (DNS) during the capture stage of two heavy nuclei can be regarded as the first step of a fusion process. However, with increasing Z of the reaction partners also their Coulomb repulsion is increasing. This can lead to the decay of the DNS before a compound nucleus is formed (quasi-fission (QF)). The velocity filter SHIP enables a background free identificat...
Thermal history and apatite fission-track ages were determined for the Kaleybar, Razgah and Bozqush alkaline intrusions which display Eocene-Oligocene stratigraphic age. These subduction-related intrusions are located in the Alborz-Azarbaijan magmatic belt which is characterized by a Paleogene magmatic flare-up associated with extensional/transtensional tectonism. The mean of Uranium content an...
The first solids that form as a cooling white dwarf (WD) starts to crystallize are expected be greatly enriched in actinides. This is because the melting points of WD matter scale Z5/3 and actinides have largest charge Z. We estimate may so they could support fission chain reaction. reaction ignite carbon burning lead explosion an isolated thermonuclear supernova (SN Ia). Our mechanism potentia...
In this study, the variants of structures are considered for fission fragments 235U nucleus caused by thermal neutrons, depending on differences in initial configuration proton, neutron and alpha particle compositions, according to a symmetrical model developed atomic nucleus. The proposed is based principles spatial symmetry analysis binding energy nucleus, taking into account quark structure ...
Introduction Dedicated experiments on nucleusnucleus collisions are the main source of our knowledge on static and dynamic bulk properties of nuclear matter. Most investigations are concentrated on the detection of nucleons, produced particles and very light fragments in fullacceptance experiments. Unfortunately, these results usually reflect the combined influence of static (e.g. incompressibi...
