摘要:Abstract(#br)We present measurements of energy loss and straggling of Si ions in gases. An energy range from 0.5 to 12 MeV/u was covered using the 6 MV EN tandem accelerator at ETH Zurich, Switzerland, and the K130 cyclotron accelerator facility at the University of Jyväskyl...

摘要:Abstract(#br)Understanding past changes in the Antarctic ice sheets provides insight into how they might respond to future climate warming. During the Pliocene and Pleistocene, geological data show that the East Antarctic Ice Sheet responded to glacial and interglacial cycle...

摘要:Abstract(#br)The Marocche di Dro deposits in the lower Sarca Valley are some of the most distinctive rock avalanche deposits of the Alps. We use geomorphology and cosmogenic 36 Cl exposure dating of boulders to divide the Marocche di Dro deposits into two rock avalanche bodi...

摘要:Abstract(#br)There is growing interest in geochronological applications of terrestrial in situ -produced cosmogenic nuclides, with the most commonly measured being 10 Be and 26 Al in quartz. To extract and then separate these radionuclides from quartz and prepare them in the...

摘要:Abstract(#br)The first basin-wide distribution of 236 U/ 238 U atom ratios and 129 I concentrations is presented for the Mediterranean Sea. During the GEOTRACES GA04S-MedSeA expedition in 2013 seawater was collected from 10 vertical profiles covering the principal sub–basins...

摘要:Abstract(#br)In 2012, Miyake et al. reported a sudden and strong increase of the atmospheric radiocarbon ( 14 C) content in Japanese cedar trees of 1.2% between AD 774 and 775. While their findings were quickly confirmed by a German oak chronology for the Northern Hemisphere...
