Fourth Generation Nuclear Weapons

  • #76
Hi sanman;

Thanks for the URL to the article. I plan on reading that article in full later this evening.

It occurred to me that indeed, attosecond laser pulses might be good to study superatoms. Other methods might include x ray diffraction crystallography, neutron diffraction crystallography, electron microscopy, or any other techniques capable of resolution on the scale of say 0.05 nanometers to 5 nanometers.

From what I gather from what I have read so far on the subject, it seems that the electronic clouds or socalled called orbitals of these superatoms seem to follow the same rules of magic numbers for single atoms in filling the energy levels or shells.

Perhaps there is an effect simmilar to Bose Einstein Condensation going on here. You have really got me interested in this subject. I will have to read more later tonight.

Regards;

Jim

why is it that when we already have powerful nuclear weapons, research is going into making more ones. isn't this like digging your own grave??????

Vals509,

Because nuclear weapons - like ANY machine - will age and deteriorate.

What do you think would happen to your car or an airliner if you just parked it and didn't
do any maintenance on it? Would you really want to fly on an airliner that had just been
sitting on the tarmac for 30 years without being flown or serviced by a mechanic?

The two things that a nuclear weapon has to do is to explode when it is commanded to;
and NOT explode when it is not commanded to under ANY other conditions. For example;
in 2007; a US Air Force B-52 mistakenly flew several nuclear weapons from North Dakota
to Louisiana. What if that aircraft had crashed? Even in a crash, you do NOT want the
nuclear weapons to explode as nuclear weapons. Suppose the safety features were
compromised due to age. You do NOT want to own nuclear weapons and then NEGLECT
them.

Contrary to popular belief; and the missives in the media; the ongoing research is NOT
about making nuclear weapons "bigger" or "more powerful". The military has better and
more accurate delivery systems - the yields of new nuclear weapons have been going DOWN
for decades. [ The actual total yield of the US arsenal actually peaked during the Kennedy
Administration ]

The number one goal of current research is to make nuclear weapons SAFER!!!

For example, the new Livermore design for the RRW features many new SAFETY
features:

"Insensitive high explosives, which are far less susceptible to accidental detonation,
will be used in RRW to replace conventional high explosives."

Unfortunately, it appears that nobody in Washington is interested in SAFER nuclear weapons.

Some like California's Senator Dianne Feinsten say that if the US makes a new nuclear weapon,
it would send the "wrong message" to the other nuclear powers. The problem for Senator Feinstein's
argument is "that ship has already sailed". The USA is the ONLY nuclear weapons state that is
NOT modernizing its arsenal:

"Currently, the United States is the only declared nuclear power that is neither modernizing its nuclear arsenal
nor has the capability to produce a new nuclear warhead," Gates told the audience yesterday.
