You're talking about the fissioning of two realities.

Subsequent studies revealed that several neutrons were also released during the fissioning, making available the opportunity for a chain reaction.

The fissioning of elements like uranium-235 and plutonium-239 is caused by their absorption of neutrons.

Retirement from passenger service started with the fissioning of Norwegian State Railways.

The next step in miniaturization was to speed up the fissioning of the pit to reduce the minimum inertial confinement time.

They decided to collect the remnant of their pure human folk and live in a completely protected region, so that there would be no further fissioning.

Therefore the fissioning of all of the fuel will result in the loss of just 240 kg of mass.

In large, megaton-range hydrogen bombs, about half of the yield comes from the final fissioning of depleted uranium.

It takes time-zones to amplify the cultural fissioning of fan-fiction or knitting into a full-blown conspiracy.

When Douglas started talking about forced coherency, congruent processing, and the fissioning of holographic personalities, my eyes glazed over.

Everybody knows that it's the fissioning of an atom bomb that triggers off the fusion of a hydrogen bomb.'

Due to the fissioning of human society along roughly racial lines, much of the Coalition's population is somewhat dark-skinned and dark-haired, or very obviously of east-Asian stock.

Tribal anthropologists have built up incredible histories of the fissioning of the Tribes since they were first recognized - most of 'em are online; you can look 'em up.

Neutrons from each neutron gun pass through and are focussed by the neutron focus lens towards the centre of primary in order to boost the initial fissioning of the plutonium.

Second, the radiation from the fissioning of the primary would be used to compress and ignite the secondary fusion stage, resulting in a fusion explosion many times more powerful than the fission explosion alone.

Relatively high concentrations of radioactive xenon isotopes are also found emanating from nuclear reactors due to the release of this fission gas from cracked fuel rods or fissioning of uranium in cooling water.

In this state, many of the neutrons released by the fissioning of a nucleus will induce fission of other nuclei in the fuel mass, also releasing additional neutrons, leading to a chain reaction.

Finally, efficient bombs (but not so-called neutron bombs) end with the fissioning of the final natural uranium tamper, something which could not normally be achieved without the neutron flux provided by the fusion reactions in secondary or tertiary stages.

The radiation from the exploding fission primary brought the fuel in the fusion secondary to critical density and pressure, setting off thermonuclear (fusion) chain-reactions, which in turn set off a tertiary fissioning of the bomb's outer casing.

"In our view, it is unlikely that one process or the other can independently account for the wide range of karyotype structures that are observed... But, used in conjunction with other phylogenetic data, karyotypic fissioning may help to explain dramatic differences in diploid numbers between closely related species, which were previously inexplicable.

Most bombs do not apparently have tertiary "stages" -that is, third compression stage(s), which are additional fusion stages compressed by a previous fusion stage (the fissioning of the last blanket of uranium, which provides about half the yield in large bombs, does not count as a "stage" in this terminology).
