Using triple-coincidence events of prompt fission gamma rays from 1995 Gammasphere data on spontaneous fission of Cf, we made a careful analysis of the yield matrix of coincident pairs of barium (Z556) and molybdenum (Z542) fission fragments. Branching from gamma bands (K52) and octupole bands (K50) are presented for even-even partners, where observable. From this reanalysis the previously prop...

Abstract We propose an efficient approach to describe the fission-fragment charge yields for actinides based on driving potential of fissioning system. Considering properties primary fission fragments at their ground states, potential, which represents energies system around scission configuration and closely relates fragments, can be unambiguously quickly obtained from Skyrme energy-density fu...

The systematic evaluations of spectrum averaged cross sections dosimetric reactions over a broad range energies were performed in 252 Cf (spontaneous fission) and 235 U(n th ,f) neutron fields. sources used this study LR-0, VR-1 zero power research light water reactors, LVR-15 10 MW reactor, source with emission specified precisely by the manganese sulphate bath. All spectral inferred from meas...

We study the role of different collective degrees of freedom in spontaneous fission process of even–even Fm isotopes. To find a proper collective space we examine a reach collection of nuclear shape parameters {βλ}, with λ=2,3,4,5,6 and 8; as well as the paring degrees of freedom i.e. proton ∆p and neutron ∆n pairing gaps. On the basis of the multidimensional dynamic–programming method (MDPM) t...

Membrane fission, which facilitates compartmentalization of biological processes into discrete, membrane-bound volumes, is essential for cellular life. Proteins with specific structural features including constricting rings, helical scaffolds, and hydrophobic membrane insertions are thought to be the primary drivers of fission. In contrast, here we report a mechanism of fission that is independ...
