Gamma-spectrometric determination of 232U in uranium-bearing materials
Jozsef Zsigrai, Tam Cong Nguyen, Andrey Berlizov
The 232U content of various uranium-bearing items was measured using low-background gamma spectrometry. The method is independent of the measurement geometry, sample form and chemi…
Basic characterization of highly enriched uranium by gamma spectrometry
Cong Tam Nguyen, Jozsef Zsigrai
Gamma-spectrometric methods suitable for the characterization of highly enriched uranium samples encountered in illicit trafficking of nuclear materials are presented. In particula…
Gamma-spectrometric uranium age-dating using intrinsic efficiency calibration
Cong Tam Nguyen, Jozsef Zsigrai
A non-destructive, gamma-spectrometric method for uranium age-dating is presented which is applicable to material of any physical form and geometrical shape. It relies on measuring…
Ellipsoidal shapes in general relativity: general definitions and an application
Jozsef Zsigrai
A generalization of the notion of ellipsoids to curved Riemannian spaces is given and the possibility to use it in describing the shapes of rotating bodies in general relativity is…
Generating New Perfect-fluid Solutions From Known Ones II
Istvan Racz, Jozsef Zsigrai
The properties of a transformation previously considered for generating new perfect-fluid solutions from known ones are further investigated. It is assumed that the four-velocity o…
