I have some understanding of Liner Energy Transfrom (LET), but when I compare it with other terminologies such as momentum, then it gets little contradicting.
For example, I know that if talk about particles and ions, then a gold ion (AU) has much higher LET than an Iron particle (Fe). And therefore AU has a much shorter penetration distance than Fe. AU gives up much of its energy in a short distance.
But what is confusing to me is that "AU" is a much heavier particle than "Fe", and when I think about this subject in terms of momentum, then AU has a higher momentum than Fe, since it is heavier.
So, in terms of classical physics and the subject of momentum, then AU, should travel a higher distance than Fe, since it has higher momentum!
Can someone please explain the flaw in my explanation, and what is it that I am not understanding correctly?
Thanks,
