6.2 THE EXPERIMENT AT VERY SMALL VELOCITIES
We introduced at the beginning of this text a modification in the De Broglie formula.
The corrected De Broglie formula is: λ = h/mf(vA)
where vA is the absolute velocity of the particle measured in the absolute referential RA.
The theoretical conditions we found this function must satisfy are:
f(0) ≠ 0
f(vA) ≈ vA for high velocities
f(c) = c
The next graphic shows an intuitive first approximation for the function:

It is proposed that the function can be obtained experimentally through the Davisson-Germer experiment at very slow velocities.
