The 40Ca(alpha,gamma)44Ti reaction in the energy regime of supernova nucleosynthesis
H. Nassar, M. Paul, I. Ahmad +20
The 44Ti(t1/2 = 59 y) nuclide, an important signature of supernova nucleosynthesis, has recently been observed as live radioactivity by gamma-ray astronomy from the Cas A remnant.…

Low-voltage nanodomain writing in He-implanted lithium niobate crystals
M. Lilienblum, A. Ofan, Ã. Hoffmann +6
A scanning force microscope tip is used to write ferroelectric domains in He-implanted single-crystal lithium niobate and subsequently probe them by piezoresponse force microscopy.…

New limit of Pu on Earth points to rarity of actinide nucleosynthesis
A. Wallner, T. Faestermann, J. Feige +9
Half of the heavy elements including all actinides are produced in r-process nucleosynthesis whose sites and history still remain a mystery. If continuously produced, the Interstel…
