The severely neutron-deficient isotopes of Element 115 made on Earth,made by bombarding those available Americium isotopes (element 95, itself made by
bombarding Plutonium with deuterons) having the greatest number of neutrons, or Berkelinium isotopes,with Calcium-48 (the heaviest stable isotope of
Calcium,with an unusually large number of neutrons for its atomic number) in particle accelerators,decay in less than 1 second, mostly by high-energy
alpha-particle emission but sometimes by spontaneous fission. This is quite unlike the Zetas' almost-stable isotope of element 115 reported by Bob
Lazar,of which kilogram quantities were kept and machined in Area 51.
Element 114,the both chemical and nuclear homolog of Lead,has a "magic shell" of 114 protons,representing a completed proton shell,and its most
stable isotope with about 1.6 times as many neutrons as protons, would have a "magic shell" of 184 neutrons,representing a completed neutron
shell,and a total atomic weight of 298. It is thus the homolog of Lead-208 which has 82 protons and 126 neutrons,also "magic numbers" representing
completed shells. The next element,Bismuth,element 83 (with one more proton than Lead-208),has the same "magic" number of protons as Lead,126,and is
the heaviest completely stable element known to Earth scientists. (Although Thorium-232,which occurs naturally in macro-quantities,comes very close to
full stability).
So,the isotope of Element 115 with 184 neutrons and atomic weight 299,which would be the both chemical and nuclear homolog of Bismuth-209,along with
Element 114 of atomic weight 298,would have unusual stability. They would quite probably be able to be handled in macro-quantities,as Bob Lazar
claims. However,just how the Zetas manage to synthesize such amounts of near-stable Element 115 with 184 neutrons is unknown. The four isotopes of
Element 115 synthesized on Earth only have 172 to 176 neutrons which represents a severe deficiency,an atomic weight of 287 to 290,and half-lives of
up to 0.173 second in the case of the one of mass 288. First officially discovered in 2003,only about 50 atoms of these isotopes have been made so
far;see
en.wikipedia.org... Wikipedia treats Lazar's claims with disdain. On August 27,2013 researchers at GSI from Lund
University in Sweden reported confirming the existence of the element,which opens the way for it to be given a proper name.
The technology required to add the further neutrons to Element 115 atoms needed for stability presently does not exist on Earth,because no known
combination of target and projectile can result in the required neutrons. It has been suggested that such a neutron-rich isotope could be formed by
quasifission (fusion followed by fission) of a massive nucleus or its alpha-decay,or multi-nucleon transfer reactions in collisions of actinide
nuclei.
In this connection,it is also noted that the heaviest easily-obtainable isotopes of Uranium (238) and all known trans-Uranium elements are the
longest-lived. For example,Plutonium-244 is the heaviest easily-obtainable of Plutonium,and also the longest-lived one,with an half-life of 82,000,000
years,just long enough for small amounts of it to still exist naturally in Uranium ores.
