BUT, neutrons have no
charge so don't seem to be deflected strongly by the charge of either
the electrons or nucleus. That's why a fission reaction is self
propagating. The neutrons released by one atom splitting - freely
enter the nearby atoms and reach their nuclei relatively unhindered.

Cliff:

My response was countering the comment that "...*absolutely nothing*
can penetrate the electron cloud to get to the nuclear core (nucleus),
without *zillions of electron volts of energy*..."

From YOUR Wik reference site:

"Since neutrons have no electric charge, they can enter a nucleus more
easily than charged particles which are repelled by electrostatic
repulsion."

A cloud of thermal neutrons thus causes Boron to produce
lots of energy, right?
