Abstract

In the bombardment of a 270μg/cm2180Hf target with48Ca projectiles at a primary beam energy of E/A=4.24 MeV/u the new nuclide225U was produced.

The experiment was performed at the velocity filter SHIP.

225U was found to decay by α emission with Eα=(7880 ±20) keV (≈90%), (7830±20) keV (≈10%) and has a half-life ofT1/2=(80 −20 +40 ms).
