“…There are many nuclei all over the nuclear chart with known high-K isomeric states [9]. It is not the purpose of this paper to discuss in detail the properties of all of them, but rather to show that the procedure discussed above works in a set of selected examples and provides a reasonable account of excitation energies of the high-K states.…”

“…Finally, we conclude that the comparison between experimental data and theoretical calculations is satisfactory, particularly taking into account that the Gogny forces were not fitted specifically to reproduced single particle properties in the region of interest.

“…In addition, their large K-value represent a strong hindrance in the electromagnetic transition strengths to the surrounding low-K states, resulting in long lifetimes that facilitate their experimental characterization while providing an excellent target for theoretical studies. High-K isomer physics can be of great importance in different scenarios like energy storage, therapeutic uses or the understanding of stellar nucleosynthesis [8,9], just to mention a few. In the later case, the high temperature environment makes possible to populate high-K isomeric states that act, thereby, as potential waiting points in the r-process mechanims-the so-called astromers [10].…”

High-$K$ isomeric states in even-even nuclei are described within a mean-field framework with full blocking and using the finite range Gogny force. Theoretical calculations of low energy spectra of several nuclei across the nuclear chart are compared with equal filling approximation results and experimental data. Despite the global character of the employed interactions, a good agreement between the different many-body methods and experimental data is found.

“…The current knowledge of lifetimes of fission isomers are very limited in the sub nanosecond region. Out of more than 40 fission isomers only a few are known in the picosecond range ( [29] and references therein). Most of such measurements were performed via indirect time measurement.…”

A new type of radio frequency (RF) timing technique is presented. It is based on a helical deflector, which performs circular or elliptical sweeps of photo- or secondary electrons, accelerated to keV energies, by means of RF fields in the 500–1000 MHz range. By converting a time distribution of the electrons to a hit position distribution on a circle or ellipse, this device achieves extremely precise timing, similar to streak cameras. Detection of the scanned electrons, using a position sensitive detector based on microchannel plates and a delay line anode, resulted in a timing resolution of 10 ps, which can be potentially improved to 1 ps. RF-Timer-based single photon and heavy ion detectors have potential applications in different fields of science and industry, which include high energy nuclear physics and imaging technologies. This technique could play a crucial role in developing of sub 10 ps Time-of-Flight Positron Emission Tomography.
