UnUnPentium is the stand-by name for Bob Lazar's mythical alien spaceship gravity drive fuel - it has been synthesised in high energy collisions between accelerated Calcium-48 ions and Americium-243 target atoms but it is HIGHLY UNSTABLE with half-lifes measured in microseconds.UnUnPentium (Uup) is the Latin name for the numbers 1, 1 and 5 - actually the 'pent' part is tagged-on Greek so that it wouldn't clash with Flerovium (previously known as UnUnQuadium) i.e. element 114.
Strange that they didn't use the Latin number for "115" as in 'one hundred and fifteen'; stupid botching geeks.
Anyway...
Uup Stability
All the reported above isotopes of element 115, obtained by nuclear collisions of lighter nuclei, are severely neutron-deficient, because the proportion of neutrons to protons needed for maximum stability increases with atomic number. The most stable isotope will probably be 299Uup, with 184 neutrons, a known "magic" closed-shell number conferring exceptional stability, making it (with one further proton outside the "magic number" of 114 protons) both the chemical and the nuclear homolog of 209Bi; but the technology required to add the required neutrons presently does not exist. This is 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, multi-nucleon transfer reactions in collisions of actinide nuclei, or by the alpha decay of a massive nucleus (although this would depend on the stability of the parent nuclei towards spontaneous fission).

Now, I'm not the sharpest twig in the woods but ... did that (above) not propose that 299Uup with its CLOSED SHELL of neutrons could well exhibit phenomenal stability.
I mean, you know, instead of SLAMMING THESE FUCKING SUB-ATOMS INTO EACH OTHER hoping something'll stick, why don't science just patiently 'coax' these atoms into relevant configurations of theoretical stability.
Softly, coaxy, makey Lazariumy.
Or just 'coax' Bob Lazar to share those few grammes of Element 115 that he alleges he 'borrowed' from S4, during his brief stint 'back engineering alien spacecraft' ahum. I wonder if Hertzan Chimera Unit theory could corroborate this stability of the 184 neutrons isotope of Uup, a neutron being a closed proton/electron cycler in HC Unit theory.
