Spontaneous fission barriers, quadrupole inertia tensor, and zero-point quadrupole correlation energy are calculated for 252,256,258 Fm in the framework of the self-consistent Skyrme-Hartree-Fock+BCS theory. Two ways of computing collective inertia are employed: the Gaussian Overlap Approximation to the Generator Coordinate Method and cranking ansatz. The Skyrme results are compared with those ...

The fission-track dating technique is an important tool to constrain the history of samples from small archaeological specimens to large geological formations. The method is based on analyzing particle tracks produced by spontaneous fission of 238 U nuclei and accumulated over time. In laboratory experiments, fission tracks can be simulated by performing irradiations with energetic heavy ions p...

The diffusion of defects (e.g., vacancies and interstitials) elements used for dating He Pb) in a mineral structure is thermal process: This the primary assumption to determine age history minerals. For instance, reconstruction, through number length distribution tracks produced by spontaneous fission 238U, obtained assuming event be only energy source shortening tracks. Here, we report new, no...

The physics and the technical algorithms of the statistical de-excitation code ABLA07 are documented. The new developments of ABLA07 have been guided by the empirical knowledge obtained in a recent experimental campaign on the nuclide distributions measured at GSI, Darmstadt. Besides distinct signatures of very asymmetric binary splits, lighter systems show clear features of multifragmentation,...

A new detector system for investigating the properties of spontaneous fission short-lived transuranium nuclei has been created. This consists an assembly double-sided silicon strip detectors surrounded by 116 proportional neutrons counters filled with 3He. The neutron registration efficiency is 54.7 ± 0.1%. tested in experiment characteristics 252No isotope. experimental data on yields are comp...
