Okay.
00:02
In this problem, we have the alpha particle inside of a, or inside of some kind of well that it's trying to tunnel out of.
00:11
This well has a length of two femtometers, and it has a height of 30 mega electron volts.
00:19
And we were asked to find the tunneling probability, also known as the transmission coefficient, for this alpha particle if it had a energy of 29 mega electron volts, so really close to the edge of the well, very close to the, very close to the, jumping out and something slightly lower 20 mega electron volts.
00:37
So the equations, we have an approximation equation for the tunneling probability.
00:43
T equals g e to the negative 2lk, rel is the width of the well, and g and k are these two coefficients.
00:51
G involves the relative energies of the well and the particle enclosed, k involves the mass of the particle and also the energies, of course.
01:02
So really this is a plug and plug and plug and plug and plug them.
01:04
We just need to insert them...
