- n. A radioactive transuranic element in the actinide series with atomic number 102, artificially produced in trace amounts. Its most long-lived isotopes are No 254 with a half-life of 55 seconds, No 253 with a half-life of 1.7 minutes, No 255 with a half-life of 3.1 minutes, and No 259 with a half-life of 58 minutes. See Table at element.
- n. a radioactive transuranic element synthesized by bombarding curium with carbon ions; 7 isotopes are known
- Named for Alfred Nobel. (Wiktionary)
- After Alfred Bernhard Nobel. (American Heritage® Dictionary of the English Language, Fourth Edition)
“Precisely measuring the mass of nobelium with our … device was a successful first step," said Block.”
“Now the international team of scientists headed by Michael Block reports it was able to trap atoms of the element 102, nobelium, in an ion trap.”
“Inside the Shiptrap apparatus, the nobelium was first decelerated in a gas-filled cell, then the slow ions were trapped in a so-called Penning trap.”
“To produce nobelium, the research team used the GSI accelerator to fire calcium ions onto a lead foil.”
“An international team of scientists headed by Michael Block was able to trap atoms of the element 102, nobelium, in an ion trap.”
“Held inside the trap by electric and magnetic fields, the nobelium ion spun on a minuscule spiral course at a specific frequency.”
“With the help of Ship, they then separated the freshly produced nobelium from the projectile atoms.”
“The measurement of nobelium (element 102) yielded an unprecedented accuracy.”
“Precisely measuring the mass of nobelium with our Shiptrap device was a successful first step.”
“The list comes to some 103, ranging from the most abundant and simplest of all, hydrogen, to the transuranic monsters, nobelium and lawrencium.”
