thank:D

just one question, Bob. in your plot you've written that the x assis is grams per cm2. the x assis' unit is centimeter, isn't it!?

thank you two guys, now i'think I'm on! now is my turn to turn it into an executable program! i will keep update you! thanks!

thanks uart, i think I got your arguments. But now I'm worried of getting lost in confusion: I've been tought that gam=E/mc2, where E is the total eneregy of the particile, E^2=p^2+m0^2, but this is in contraddiction with "your" definition of E=m0(gam-1) I apologize for my insistence, but...

hi bob! step by step, you are saving my week! :D thanks for the program. however, I don't know true basic. btw, I'm trying to understand the process to translate it in C. let's try to sum up: - you define all the stuff.. - you define the starting point for x and E. - an iteration starts, from 0...

so bob, the fact that the plot represent only one particle is not a problem. I've just to show the difference in behaviour of different particles. the point is: what program did you used? can you post it!? thanks!

hi bob, first, thank you, really so much! even if i don't know the program you used to plot the first graph, that is the "classical" BB formula, i'd already achieved that result and that graph. the problem i have now is to obtain the second graph you posted. have you obtained it using geant (i'm...

i want to plot the energy-loss vs penetration energy that is wat you see here: http://www.med.harvard.edu/JPNM/physics/nmltd/radprin/sect7/7.1/bragg.GIF (i suppose..)

sorry, but what do you mean?

uhu.. so complicated? i try to explain a little more.. i'm studying Hadrontherapy, i.e. the use of light ions or protons against tumors. this kind of particles are characterized by a particular form of loosing-energy curve. as you se here http://www.gsi.de/forschung/bio/e-deposition_small.jpg...

Goodmorning everyone, I'm new to this forum! I'm graduing in physics in Italy, and I have this problem. I want use root to plot the Bragg curve for different kinds of particles, with different initial conditions. the problem is, which function have I to plot...
