We have performed precise dc magnetization measurements for a single crystal of UBe(13) down to 0.14 K, up to 80 kOe. We observed a magnetic anomaly in the superconducting (SC) mixed state at a field, named H(Mag)(*) (~ 26 kOe, at 0.14 K), implying that UBe(13) has a magnetically unusual SC state. We studied the magnetization curves of UBe(13), assuming that the H(Mag)(*) anomaly originates fro...

A new method for determining the hyperfine anomaly, without knowing the nuclear magnetic moment, is used for the first time on a series of unstable isotopes. The relative large number of experimental data in Eu makes it possible to determine the hyperfine anomaly for a number of unstable isotopes. Calculations of the Bohr-Weisskopf effect and hence the hyperfine anomaly has been performed using...

We have applied an automatic interpretation method of potential data called AN-EUL in unexploded ordnance (UXO) prospective which is indeed a combination of the analytic signal and the Euler deconvolution approaches. The method can be applied for both magnetic and gravity data as well for gradient surveys based upon the concept of the structural index (SI) of a potential anomaly which is relate...

Chemically peculiar stars in the magnetic sequence can show the same isotopic anomaly in calcium previously discovered for mercury-manganese stars in the non-magnetic sequence. In extreme cases, the dominant isotope is the exotic 48 Ca. Measurements of Ca  lines arising from 3d-4p transitions reveal the anomaly by showing shifts up to 0.2 Å for the extreme cases—too large to be measurement er...
