I will check the book for sure. Thanks a lot for your help. I really appreciate that.

Thanks a lot

Any resource detailing that ? So grateful

Do you have any resources that detail this? Also i don't get the relation beween the choice of C and the movement in a staight line? Very grateful for your answer.

I didn't understand what you mean here. Would you please clarify. Thanks a lot

Hello everyone, I found in the PDG booklet that pi 0 decay into e+ e- gamma is more likely to happen than to e+ e- only ..is there a reason that favorises the first decay?

Hello everyone, How does Einstein established the equivalence between mass and energy, or in other words what is the fact that proves this.And why the constant is not just C but C square. Why C anyway ??

ok, i get that, so if we say: the energy outside is equal to T+V (taking V positive) we will get an energy for the alpha particle greater than the potential wall..in other words V is negative?

so it's not V-T (because i couldn't get why) but if it's V+T i accept it, i thought that the particle can get out even if it has an energy lower than the potential well because of tunneling effect! according to what you said it must have an energy greater or equal to it! is that right?

the depth is postive,the problem is that i don't get why? i found V-T?

i'm struggling to understand this: an alpha particle is emitted with a kenetic energy T, if we know the value of the depth of the nuclear potential well V, we find the kenetic energy of the alpha particle inside the nuclei by substructing V-T , would you please explain this to me? Thank's

So the corrected stirling is the most accurate formula to use if we want better precision?

Just a question, How can we know that we should get to next term of the approximation ( without calculating and finding a wrong result)?

oh yes yes that's ok i found P=0.08 ...that was Log P which is negative sorry ...Thank you

I used the next term too and i got a negative result ! I got 1/2 Log2 - 1/2 Log 100π !
