Joshua Patin, Ph.D., Nuclear Chemist, Lawrence Livermore National Laboratory, Livermore, California: "It was an experiment that had been chosen because of its decay through Element 113. So, there was a notion at the beginning of the experiment that if we saw the decay of Element 115, we would also see the decay of Element 113. And those had not been seen before.
AND IN THE HYPOTHESIS OF THESE HIGHER ELEMENTS, ISN'T IT TRUE THAT CONCERNING THE PERIODIC TABLE, PHYSICISTS HAVE SPECULATED THERE WOULD BE A POINT SOMEWHERE AROUND ELEMENT 115 OR HIGHER WHERE THERE WOULD BE MORE STABILITY AND MAYBE EVEN A LONGER LIFE?
True. When you are looking at the various isotopes that can be produced of elements 114, 115, 116, even 113, there are some isotopes that have been predicted to have very long half lives. The region where initially it was proposed to have more stability was Element 114 with 114 protons. But we need to put more neutrons in (to balance out the protons) and that's a whole other area in terms of what kind of experiment we want to perform.
With the current level of technology and types of targets like the americium 243 and the beams that we used of the calcium 48, we can't necessarily quite get there, but we can get close. That's why we've done these experiments.
By doing the Element 115 and Element 113 experiment and in the past with the group of Element 116 and 114, we've shown that there is this enhanced area of stability.
COULD THERE BE AN ELEMENT 115 ISOTOPE THAT IS SOLID AND CAN BE HELD IN THE HAND?
Some day down the road, I think so. If it's true that we find something that is long enough lived. To hold something in your hand, you would need a significant quantity of these atoms. We've produced four atoms of Element 115 in a month. It would take you don't have enough time in the rest of the universe to create enough that you could hold in your hand through these same kinds of production methods (that we are using). That's why I say a future technology might allow us advances in terms of how much can be produced and the target material, maybe a better way of producing but somewhere down the road, there might be a possibility, sure.
AND SO WITH ADVANCED TECHNOLOGY, YOU MIGHT BE ABLE TO PRODUCE ELEMENT 115 IN ENOUGH QUANTITY THAT IT COULD BE SOME KIND OF SOLID MATTER THAT COULD BE WORKED WITH AND APPLIED IN OTHER WAYS?
Exactly."

I don't know. That part of the theory I don't know.

I love this part..
The superheavy Element 115 was created in a Dubna, Russia, cyclotron by slamming a rare isotope of calcium that has 20 protons at americium which has 95 protons.

You can sidestep all you want. I'm waiting for an answer.

So.. you question the people involved in the experiment itself?
Why don't you enlighten me, with a scientific rebuttle of Joshua Patin's views of element 115?
A couple of minor points...You're supposed to use the quote tags for quoting other ATS members, but you quoted an external source which requires the "EX" or "external" tags, AND, you're supposed to provide the source and I don't see a link but I ran a search and found this one, is this it?

So he doesn't know enough about what the theory predicts. If you're going to quote a "real scientist" how about finding one that at least knows what the theory predicts? And even then it's just a prediction from what appears to be a speculative theory.
HYPOTHETICALLY IT COULD BECOME A STABLE NON-RADIOACTIVE PIECE OF MATTER, ELEMENT 115?
I don't know. That would be something for us to discover. I don't know enough about what the theory predicts for the region (on the Periodic Table) to say if that could happen. I don't know if the life times are long enough to get to the point that they are stable and not radioactive."
So even in the center of the island we have no idea whether the half lives will be short or long, but my interpretation of that quote is that nobody is really expecting them to be stable and we're uncertain about exactly how unstable they will be.
The half-lives of nuclei in the island of stability itself are unknown since none of the isotopes that would be "on the island" have been observed. Many physicists think they are relatively short, on the order of minutes or days.[1] However, some theoretical calculations indicate that their half-lives may be long, on the order of 10^9 years.

How Tough Is it to Build a Dirty Bomb?
Read the Transcript: to.pbs.org...
Science correspondent Miles O'Brien examines the threat that radioactive "dirty bombs"could pose to cities in the U.S., and what's being done to prevent a radiological attack from happening.
BOB LAZAR, United Nuclear: We pretty much try and carry everything in the scientific realm.
MILES O'BRIEN: Cummings got some of his radioactive material from this man, Bob Lazar. He owns a company called United Nuclear. Housed in a small storefront in tiny Laingsburg, Mich., he does a good business on the Web selling all kinds of chemicals, equipment and oddities for scientific hobbyists.
BOB LAZAR: These are isotopes.
MILES O'BRIEN: He sells them to the general public, and it's all perfectly legal.
BOB LAZAR: Really, if you want to build a dirty bomb, buying the radio isotopes isn't the route to go.
MILES O'BRIEN: Why not?
BOB LAZAR: Well, first of all, you can't get enough radioactive material. And, to disperse it, you need something water-soluble would be better, because then you can absorb it into something that, with a bomb, you can disperse it over to a large area.
Having big plastic disks with an invisible amount of a speck of radioactive material in it is pretty useless in -- in making a dirty bomb. And -- and you would have to order literally hundreds of thousands of them.
