The more neutron rich even-even tungsten isotopes are the only nuclei accessible by(particle, xn) reactions in the rare-earth region of deformation for which high-spin data on the yrast bands have yet to be reported. The tungsten isotopes are of some interest in this regard, because they bridge a region between no back-bending in the more neutron-rich hafnium isotopes, and a region of sharp yrast anomalies in the osmium isotopes. 2, record 1, English, - yrast

L'énergie d'excitation du noyau cible (différence entre l'énergie du noyau et celle de ce même noyau dans son état fondamental) peut être séparée en deux parties. La première correspond à l'énergie minimale qu'il faut fournir au noyau pour qu'il ait un moment angulaire donné. On appelle le reste énergie d'excitation interne. Si ce reste est nul, on dit que le noyau est dans un état yrast (superlatif de l'adjectif suédois yr, qui veut dire étourdi ou saoulé d'avoir tourné trop vite). 2, record 1, French, - yrast

Record number: 4, Textual support number: 1 CONT
A Superconducting Tunnel Junction(STJ-or Josephson junction) consists of two thin films of a superconducting metal such as niobium, tantalum or hafnium separated by a thin insulating layer. When operated at temperatures well below the superconductor's critical temperature(typically below 1 K), the equilibrium state of the junction is easily perturbed by any photon striking it. By applying a small bias voltage across the junction and a suitable parallel magnetic field to suppress the Josephson current, an electrical charge proportional to the energy of the perturbing photon can be extracted from the device. 1, record 4, English, - superconducting%20tunnel%20junction
