Sentences with phrase «uranium nucleus»

Except that he hadn't actually done so — his «new elements» were actually familiar elements produced by the splitting of the uranium nucleus.

The idea was to increase the neutrons» chances of being absorbed by another uranium nucleus.

Meitner and Frisch were able to provide an explanation for what he saw that would revolutionize the field of nuclear physics: A uranium nucleus could split in half — or fission, as they called it — producing two new nuclei, called fission fragments.

Then they'd run into other uranium nuclei and induce a second round of fission reactions, emit even more neutrons, and on and on.

Other gamma rays split uranium nuclei in a layer behind the gold, splitting them into lighter elements.

The radiation from decaying uranium nuclei breaks apart sulfur and water molecules in the stone, producing molecular fragments such as sulfate and hydrogen peroxide that are excited with internal energy.

Not exact matches

From the equivalence of mass and energy in relativity theory, together with theories about the fission of heavy nuclei, it was predicted that if a certain mass of uranium was brought together, an explosion would occur; surely all observers in the New Mexico desert on that day in 1943 could agree as to whether an explosion occurred.

At the very bottom of the board we have the 92 simple chemical elements (from hydrogen to uranium) formed by groups of atomic nuclei together with their electrons.

When bombarding uranium with neutrons, Hahn had made some surprising observations that went against everything known at the time about the dense cores of atoms — their nuclei.

As a neutron is bombarded into the U-235 nucleus, it produces a Uranium - 236 (U-236) nucleus and gives it extra-energy to help it split into two separate fragments.

These include the Facility for Antiproton and Ion Research (FAIR) being built in Darmstadt, Germany, which uses heavy nuclides such as uranium for the initial collisions with light nuclei.

All reactors produce energy by splitting the nuclei of heavymetal (high - atomic - weight) atoms, mainly uranium or elements derived from uranium.

As the atoms decay, they release high - speed helium nuclei and then become smaller uranium atoms.

Fusion is the opposite of fission, which frees energy when an atom like uranium splits into two smaller atomic nuclei.

A nuclear reactor derives power from the fission of four different atomic nuclei: uranium - 235, uranium - 238, plutonium - 239, and plutonium - 241.

One interesting feature of the synthesis of heavy elements by neutron capture at a high rate in a supernova explosion is that nuclei much heavier than lead or even uranium can be fashioned.

Most of the total Uranium - 235 breaks down into smaller nuclei during fission.

As its name implies, this process must occur rapidly in order to build up to very heavy, neutron - rich nuclei that then decay into heavy elements, such as uranium, which has 92 protons compared to iron's 26.
