Abstract

LOREX, the acronym of LORandite EXperiment, is the only long-time solar neutrino experiment still actively pursued. It addresses the long-time detection of the solar neutrino flux with the thallium-bearing mineral lorandite, TlAsS2 at the mine of Allchar, FYRMacedonia, via the neutrino-capture reaction 205Tl+νe→205Pb+e−. The final step of LOREX would be the extraction of lorandite samples and the quantitative determination of the ratio of 205Pb/205Tl atoms providing the product of solar neutrino flux and neutrino-capture cross-section, integrated over the age of lorandite (about 4.3×106 y). There is an unprecedented low threshold of only 50 keV for solar pp-neutrinos, to be compared with 232 keV of the GALLEX and SAGE experiments. Moreover, LOREX would be unique in view of providing the mean luminosity of the sun over the last 4.3 million years. This paper presents new data providing an accurate geological age of mineralization at Allchar, and in particular a lower limit of 36 m/106 y for the erosion rate, based on Accelerator Mass Spectrometry of 26Al and 53Mn samples taken from the mine of Allchar. This data allow first realistic conclusions on the feasibility of the LOREX project. The amount of 205Pb due to fast cosmic rays (e.g. muons), strongly depends on the depth at which the mineral existed from the time of its formation to the present day. For the mineral mined at the present-day depth this contribution then depends upon the average erosion rate at this particular location. A reliable determination of the erosion rate is, therefore, indispensable for a proper estimate of the background of 205Pb induced by cosmic radiation. Provided that this lower limit of 36 m/106 y can be corroborated by the mandatory measurement of additional probes, it is expected to reach a signal-to-background ratio equal or better than one. Finally, it is discussed how to get the still unknown capture probability of solar pp-neutrinos from 205Tl into 205Pb, in particular into its first excited state at E*=2.3 keV.

Abstract

LOREX (LORandite EXperiment) addresses the determination of the solar (pp) neutrino flux during the last four million years by exploiting the reaction 205Tl+νe→ 205Pb+e-with an incomparably low-energy threshold of 50 keV for the capture of solar neutrinos. The ratio of205Pb/205Tl atoms in the Tl-bearing mineral lorandite provides, if corrected for the cosmic-ray induced background, the product of the flux of solar neutrinos and their capture probability by205Tl, averaged over the age of lorandite. To get the mean solar neutrino flux itself, four problems have to be addressed: (1) the geological age of lorandite, (2) the amount of background cosmic-ray-induced205Pb atoms which strongly depends on the erosion rate of the lorandite-bearing rocks, (3) the capture probability of solar neutrinos by205Tl and (4) the extraction of lorandite and the appropriate technique to “count” the small number of205Pb atoms in relation to the number of205Tl atoms. This paper summarizes the status of items 1 (age) and 3 (neutrino capture probability) and presents in detail the progress achieved most recently concerning the items 2 (background/erosion) and 4 (“counting” of205Pb atoms in lorandite).

Abstract

The electronic structure of superheavy elements (Z ≥ 104) and their chemical properties are dominated by relativistic effects. Recently two superheavy elements were recognized by the IUPAC and named flerovium (Fl, Z = 114) and livermorium (Lv, Z = 116). Fl is the heaviest element with which chemical experiments were performed. Here, we report on experiments that help answering the long-standing question whether Fl behaves rather like a noble gas or like a metal.

Abstract

The decay of the very neutron-deficient isotope 101 Sn was studied at the GSI on-line massseparator using silicon detectors for recording charged particles and germanium detectors for gamma-ray spectroscopy. Based on the beta-delayed proton data the production cross-section of 101 Sn in the 50 Cr+58 Ni fusion-evaporation reaction was determined to be about 60 nb. The half-life of 101 Sn was measured to be 1.9±0.3 s. For the first time beta-delayed gamma rays of 101 Sn were tentatively identified, yielding weak evidence for a cascade of 352 and 1065 keV transitions in 101 In. The results are discussed by comparing them to predictions obtained from shell-model calculations employing a new interaction in the 88Sr to 132Sn model space.

Abstract

Seaborgium (element 106) was studied in comparison with tungsten in the O2-H2O(g)/SiO2(s)-system using high-temperature on-line isothermal gas chromatography. The 21-s nuclide 266Sg was produced in the 248Cm + 22Ne reaction at a beam energy of 119 MeV. The reaction products were continuously transported by a He(MoO3)-jet to the chromatography apparatus HITGAS. Group 6 element oxide hy-droxide molecules volatile at temperatures above 1000 K were formed at 1325 K by adding humid oxygen as reactive gas. 266Sg was unambiguously detected after gas chromatographic separation by measuring 266Sg-262Rf mother-daughter a-sf correlations. The experimental results demonstrate the volatility of seaborgium in humid oxygen, presumably as seaborgium oxide hydroxide as typical for both uranium (VI) and the group 6 elements.
