How did I get into that discussion? Is that some kind of Dewinduction?

It is very expensive and difficult to work with. The contact alloy is more likely a CuNiSn, or similar. LCP is very common in small connectors and valued for its high temperature characteristics and resistance to warpage in small geometries. It is a bit temperamental if there are uneven wall thicknesses. Leif, if you can tell me the connector mfr and part number I might be able to do some investigation for you and give you hints Doug Erb Senior FAE Hirose USA -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Inge Sent: Friday, May 15, 2009 2:47 PM To: [log in to unmask] Subject: Re: [TN] NTC - Friday Trivia Question Now Dave, you made me curious. I understand the neutron irradiation that lifted Uranium to another isotop level, but HOW did they determine that they had a new element? I thought that was what you meant with sampling.

Any explanation beyond that means I have to open up a few text books and do some reading! My curiosity is for the folks on the airplane conducting the air sampling - just what were the health effects of that exposure!

Jarre uses lots of lasers in his shows. Laser..hm...photons... exitation...gamma radiation....hydrogen bomb..hmm...Einsteinium must have higher energy than Uranium when electrons fall back to origin place in the orbit after a high energetic bombardment......so they must have used ionized Uranium that was bombarded with gamma that lifted electrons to higher orbit , then accelerated these ions through a magnetic field and registered a energy count higher than what had been seen before...I give up. Dave, you got to tell us. I make things more complicated than what's needed. I'm sure you'll tell us about a simpler way. Hmm...I don't remember the deterioration of Einsteinium...guess it starts fall apart very rapidly. Does it have anything to do with Geiger-Muller detecting? Hmmmmmmmmm...now wait a little. I'm a stupid. They must simply have decided the density! But could they...the new element had short life..OK...I come no closer.. May someone else crack the nut. Tomorrow I'll have a look in my old books of Physics..
