Because the Dubna team used a different target and projectile than the Japanese,
all of their decay chains end in the fission of dubnium.
But none
of the decay chains detected included an anchor decay.
Your turn: Figure out
all of the decay chains to make sure you know the stable end product and whether or not there are any radioactive intermediates.

(CNN)-- Billy Graham, the dean
of American evangelists, has once again broken his usual silence on hot - button issues, defending the president
of the Chick - fil - A restaurant
chain for his opposition to same - sex marriage days after issuing a letter decrying what he sees as the nation's moral
decay.
The death
of Jesus was a rescue operation where He broke into the prison
of our bondage where we were rotting in filth and
decay, and through His life, death, and resurrection, demolished our
chains, picked us up on His shoulders, and carried us to freedom outside
of the prison walls.
While this system has broken down, it has
decayed not simply because the animal spirits
of Wall Street did not temper their zeal with a respect for greater community, but because American citizens embraced the pact that was offered them: an endless supply
of baubles from citizens in
chains so long as they refused to speak out in the pulpit against the notion that greed is good, that profit maximization is the chief end
of man.
Instead, physicists must search through the debris
of many different types
of particle
decay to find precise combinations
of by - products that the Higgs would produce — and different
chains of particle
decays may well have the same signatures.
Many
of the universe's heaviest elements form primarily through the r - process, a
chain of reactions through which atomic nuclei climb the periodic table, swallowing up neutrons and
decaying radioactively.
And if one member
of the
chain is a nucleus that has been previously studied, then its
decay properties anchor the whole sequence in reality.
However, the chemistry
of dubnium had been studied previously, so the team was able to identify that final single atom in the
decay chain by chemical means before it fell apart.
It produces Lead as the final stable element
of this Alpha
decay chain.
Radiometric or radioactive dating steps jump to radioactive

decay chain from lead - radiometric or radioactive dating steps step in such a
chain is characterized by a distinct half - life.
The method relies on two separate
decay chains, the uranium series from 238 U to 206 Pb, with a half - life
of billion years and the actinium series from 235 U to 207 Pb, with a half - life
of 710 million years.
U — Th — Pb Geochronology Blair Schoene, Princeton University, Princeton, NJ, USA the most commonly utilized mineral for U — Pb dating The method relies on two separate

Hung haphazardly from the ceiling with
chains and electrical cords, the sheets
of foil insulation lining, cardboard, and other
decaying materials evoke both the inhumanity
of frontier justice and the strange hopefulness
of spring cleaning.
The approach I would start with is to look at the various stable good nuclei, find which isotopes with short half lives
decay to that state, and trace back the
chain of reactions to see what kind
of isotopes we might want to produce by bombarding some other isotopes with neutrons... and maybe some isotope
of lead or mercury would do the trick.
