Rotational fission of trans-Neptunian objects:the case of Haumea
Kuiper belt general – Kuiper belt objects individual Haumea – minor planets, asteroids general
2015/12/25
We present several lines of evidence, based on different kinds of observations, and we conclude that it is likely that rotational fission has occurred for a fraction of the known trans-Neptunian objec...
Nanostructured Singlet Fission Photovoltaics Subject to Triplet-Charge Annihilation
singlet exciton fission photovoltaic triplet charge pentacene
2014/8/21
Singlet exciton fission is an efficient multiple-exciton generation process that is vulnerable to a characteristic loss process: triplet-charge annihilation. This loss process is characterized in sing...
A transferable model for singlet-fission kinetics
transferable model singlet-fission kinetics
2014/8/21
Exciton fission is a process that occurs in certain organic materials whereby one singlet exciton splits into two independent triplets. In photovoltaic devices these two triplet excitons can each gene...
视频：南京大学大学物理学第66讲 Fission and fusion。
Oil tankers fitted with neutrino detectors, hundreds of thousands of tonnes in mass, could be floated offshore to check for undeclared nuclear fission reactors. That's the idea of physicists in France...

Multi-modal analysis for low energy neutron-induced fission of 235U
235U (n, f) multi-model prompt neutron fragment property
2009/12/24
Low energy neutron induced fission of 235U is studied in the framework of the multi-modal fission model. The fission fragment properties, such as the yields, the average total kinetic energy distribut...
A fission track data compilation for Fennoscandia

2009/12/2
A compilation of fission track data is presented here to show from where fission track data are available in Fennoscandia and to highlight potential targets for future research. Because of the relativ...
Sequential And Double Sequential Fission Observed In Heavy Ion Interaction Of (11.67 MeV/u)197Au Projectile With 197Au Target
Heavy Ion Interaction mica track detector multi- pronged events sequential fission double sequential fission
2010/7/8
The heavy ion interaction of 11.67 MeV/u 197Au+ 197Au has been investigated using mica as a passive detector. By employing Solid State Nuclear Track Detection Technique the data of elastic scattering ...
Isospin effect on spontaneous fission half-lives of even-even nuclei
isospin effect WKB approximation spontaneous fission half-lives
2009/8/14
By using a new five-parameter formula derived from the WKB approximation, we systematically calculate the spontaneous fission half-lives of even-even nuclei with Z=90—108. The isospin effect is taken...
