An unstable isotope Lu-176 decays to Hf-176 with a half-life of approximately 4×10^10 y. The Lu-176 could be used as a nuclear cosmochorometer for dating the nucleosynthesis event before the solar system formation. However, the half-lives measured with various nuclear experiments are inconsistent with each other. Furthermore, the half-lives evaluated from the Lu and Hf isotopic abundances in...
Recent models for evolved low-mass stars (with M <=3 Mo), undergoing the asymptotic giant branch (AGB) phase assume that magnetic flux-tube buoyancy drives the formation of 13C reservoirs in He-rich layers. We illustrate their crucial properties, showing how the low abundance of 13C generated below the convective envelope hampers the formation of primary 14N and the ensuing synthesis of...
Neutrino and astroparticle physics project BAIKAL-GVD is aiming at the identification of still unknown astrophysical sources of ultra-high energy (exceeding tens of TeV) neutrinos. The identification of sources will help to elucidate mechanisms of galaxies creation and evolution. Baikal-GVD - flagship experiment of JINR with its leading role in international collaboration. New experience in...
