The studies of complete fusion reactions leading to production of superheavy elements (SHE) with Z ≥ 108 is extremely difficult due to very low production cross sections. Excitation function measurements of evaporation residues from a fusion reaction together with measurements of the fusion – fission cross section provide important experimental information(More)
Terbium-149 is among the most interesting therapeutic nuclides for medical applications. It decays by emission of short-range α-particles (Eα = 3.967 MeV) with a half-life of 4.12 h. The goal of this study was to investigate the anticancer efficacy of a 149Tb-labeled DOTA-folate conjugate (cm09) using folate receptor (FR)-positive cancer cells in vitro and(More)
The periodic table provides a classification of the chemical properties of the elements. But for the heaviest elements, the transactinides, this role of the periodic table reaches its limits because increasingly strong relativistic effects on the valence electron shells can induce deviations from known trends in chemical properties. In the case of the first(More)
Experimental investigations of transactinoide elements provide benchmark results for chemical theory and probe the predictive power of trends in the periodic table. So far, in gas-phase chemical reactions, simple inorganic compounds with the transactinoide in its highest oxidation state have been synthesized. Single-atom production rates, short half-lives,(More)
BACKGROUND Terbium has attracted the attention of researchers and physicians due to the existence of four medically interesting radionuclides, potentially useful for SPECT and PET imaging, as well as for α- and β(-)-radionuclide therapy. The aim of this study was to produce (152)Tb (T 1/2 = 17.5 h, Eβ+av = 1140 keV) and evaluate it in a preclinical setting(More)
The unambiguous identification of new superheavy elements (SHE) is a very difficult task for both, physicists and chemists due to very low production rates, absence of a link to known isotopes, and unknown chemical, and decay properties. Chemical studies of SHE are of great importance because they can identify the proton number of the studied isotopes.(More)
During the TASCA commissioning phase competitive tests of two types of focal plane detectors for TASCA – a Position Sensitive Silicon Stripe Detector (PSSSD) and a Double Sided Silicon Strip Detector (DSSSD)-have been performed. The DSSSD proved to be more reliable and more sensitive for the detection of decay chains due to the high granularity of the(More)
BACKGROUND The targeting of the prostate-specific membrane antigen (PSMA) is of particular interest for radiotheragnostic purposes of prostate cancer. Radiolabeled PSMA-617, a 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA)-functionalized PSMA ligand, revealed favorable kinetics with high tumor uptake, enabling its successful(More)
