The free neutron cell carries a varying amount of kinetic energy in the form of relative motion from the moment of its emission from an atomic nucleus or galactic core until its spontaneous transformation.
The kinetic energy carried by the neutron’s inertial mass is an additional variable “environmental” form of bound rise energy, and is accounted for separately, as we balance the movement/energy books before and after transformation. After transformation the kinetic energy of the neutron whole is transferred as momentun to the proton mass and the electron mass.
As it begins its free life, the neutron cell is emitted from a nucleus of a radioactive atom with considerable speed; from around 14,000 kilometers per second, to around 52,000 kilometers per second. This is 5% to 17% of the speed of light. It is speculated that neutrons emitted from galactic supercells (the black holes of current science) have much higher velocities.
Kinetic energy is directly related to the physical size of the free neutron cell. The faster a neutron cell travels relative to a frame of reference, the smaller its size relative to that frame of reference. What changes is the density of the cell plasm matter [3a]. The faster the neutron, the denser the plasm, and the smaller its volume. The core and membrane matter with their absolute density, always contribute the same fixed volume to a neutron cell.
Neutron cell size can be also be calculated as a De Broglie “wavelength”, which Neu Theory considers as equivalent to the neutron’s physical diameter.
For example, a neutron cell traveling at the speed of 52,000,000 m/s (0.17 c) has a diameter of 7.6 x 10-15 m which is about 30 % larger than a lead nucleus with a diameter of 11.0 x 10-15 m.
Conversely a neutron cell with a diameter of 62 x 10-12 m, the size of a helium atom , travels at the speed of 6,385 m/s.
An ultra cold neutron cell with a diameter of 1 x 10-7 m, the size of the largest molecules, travels at the relatively slow speed of approximately 10 m/s. Some human athletes have run the 100 meters dash faster than that! The current world Olympic record of 9.69 s was set by Usain Bolt of Jamaica in 2008.
The kinetic energy of the neutron is also called its “temperature.” High velocity neutrons with small diameters are “hot” neutrons. Low velocity neutrons with large diameters are “cold” neutrons. Very low velocity neutrons with the largest diameters are “ultra cold” neutrons.
