Several observations of the Nb long-lived Mossbauer phenomena are presented, in consequence of an irradiation increased by an order of magnitude compared with previous work. These are 1) two β decays of 182Ta and 92mNb are enhanced, i.e., 182Ta is now 200 times faster than in previous results while 92mNb is twice as fast as normal; 2) γs emitted from two β decays compete to eject electrons in a...

The atomic structure of soft magnetic iron-aluminum alloys is studied by X-ray diffraction and nuclear gamma-resonance spectroscopy. concentration dependence the body-centered cubic lattice constant short-range order (SRO) parameters in region a disordered solid solution monitored. It shown that range from 3 to 18 at.% Al, increases almost linearly. Discrete decomposition gamma resonance spectr...

Tamusu area in Inner Mongolia is one of the favorable site candidates for high level radioactive waste (HLW) repository, which requires a stable regional tectonic environment. Field investigation, mossbauer spectroscopy, major elements, carbon and oxygen isotope quartz micro morphology fault gouge host rock three faults candidate were conducted. The results show that F2 F7 on north south sides ...

Nickel ferrite nanoparticles 4 nm in size were synthesized by chemical deposition. Subsequent annealing at T=700 o C for 5 h led to an increase the particle 63 nm. The Mossbauer spectra and frequency-field dependences of ferromagnetic resonance have been measured. It has shown that freshly prepared powders are superparamagnetic room temperature. kinetic heating mode a frequency 8.9 GHz was foun...
