In nuclear physics, a cross section is essentially the probability that a nucleus will interact with something. An isotope with a high fission cross section, like U-235, is very likely to absorb a thermal (slow) neutron and undergo fission. The cross section has units of area, usually cm2, which is where the name comes from. When the cross section is multiplied by the neutron flux, the product is the fission rate, or number of fissions per second.
What else can I help you with?
What do control rods in a reactor contain?
The 2 most common materials are cadmium or boron, due to their large neutron absorption crosssection.
Where do you get nuclear fission?
You get nuclear fission in:nuclear fission reactorsatomic fission bombs
What is the crosssection perpendicular to the base of a triangle?
A triangle does not have a cross-section but the perpendicular line of a right angle triangle meets the base at 90 degrees.
Prokaryotic cells reproduce by a process called?
binary fission
What is fission product?
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
What is the splitting of an atoms nucleus into two smaller nuclei is called?
nuclear fission
Where does fission occour?
Nuclear fission occurs in fission reactors, a type of nuclear reactor, and in fission bombs, more commonly knows as atomic bombs.
For a sustainable fission reaction each fission must produce exactly additional fission reaction(s).?
A stable nuclear fission reaction will be sustained if every fission produces one additional fission reaction.
Does an amoeba reproduce by fission?
Yes, but not fission on the atomic level. Fission simply means to split apart.
