Kegunaan isotop disprosium
- The isotopes of dysprosium are highly magnetic and have been the subject of physics research involving interactions of isotopes and the structure of lattice supersolids (spatially ordered material with superfluid properties, i.e. zero viscosity). The Magneto-Optical Trapping (MOT) chamber is used for slowing atoms (isotopes) to study the physics of neutral atoms by using a laser light to cool atoms (“Doppler cooling”) and magnetic quadrupole fields to slow and “trap” the neutral atoms (Fig. IUPAC.66.1),. 164Dy has a large neutron absorption cross section, so dysprosium is used for control rods. 161Dy has been a key isotope for studying the Mössbauer Effect, which is the resonance and absorption of gamma ray emissions on nearby atoms in a solid state.
