naiveBen, did you mean that it has to do with the free path length of the ion? I think, dx in the equation is a small step the ion make, whatever the interaction that has happened to the ion, and in any direction. it's computational step, the smaller step we choose, the graph is more smooth...

Thank you. :-D Eko S

Hi Bob, Is it okay if use TZ for air with (0.8*14+0.2*16) and TA with (0.8*28+0.2*32)? The graph is't change much. And if I change the alpha energy to 5.49 MeV, the graph shows that the projected range is 3,83 cm. Eko

Thank you very much Bob. You've been very helpful. I don't have Truebasic, so I write your code in Excel worksheet. I've tried write your code in Python, but this program also new to me, I can't figure out how to do the condition in the loop part. I attach the picture from Excel worksheet, and...

Thank you very much Bob, I am new to this topic. I am studying the interaction of radiation with matters. I've got the paper that you suggested, and I'll try to find a copy of the book. I am sorry if I'm asking too much, but if you can give me short explanation on how to get Bragg curve for...

Thanks Bob, I rewrite your code in Python, and get same graph. Here is the code : import math mpc2=938.27 #proton mass in MeV mec2=0.511 #electron mass in MeV re=2.817e-13 #clasical electron radius rho=1 #density of water in grams per cm3 IZ=75 #ionisation...

Hi, If I want to use alfa particle and air as target, which one do I have to change in that code? Thanks.
