Dear "Javier Lopez":

using the formulas for calculating x-sections can be difficult besides wasting your time . now I'll help you .

1. go to the website below:

http://www.nndc.bnl.gov/exfor/endf00.jsp

2.choose " sigma retrieval " button .

3.choose " advance retrieval" button in the new page which has been opened just after passing no. 2 .

4.in the new page, tick in " proton reaction" empty button, and erase other ticks if you see in the page except "ENDF/B-VII.1". then write mass and atomic number of your "target" click " submit".

5.find out your cross sections in barn . 

"you can ask your questions if you get in to the trouble."

Dear Mahsa,

I did not found there eleastic reactions for p+B11 and p+Li6, only reactions p+Li6 (that I had from a similar web), I left in blank the target to find all data inside

Perhaps dose data does not exists because there is a formula to obtain them

Dear Javier Luis López,

Here http://cdfe.sinp.msu.ru/cgi-bin/exfV3.cgi?inpart1=&atarg=11&ztarg=5&author=&inpart=P&outpart=EL& you may find available data on the 11B(p,p) reaction, it includes angular distributions at fixed energy as well as energy dependance of the d\sigma/d\Omega(\theta).

The page was generated by the service http://cdfe.sinp.msu.ru/services/unifsys/index.html

You may use it in order to get other data.

Thank you very much, Dr. Denikin

Dear Javier,

Check the following paper: F. E. Portillo et al., NIMB 305 (2013) 16-21. Data for the kinematically inverse reaction p(6Li,6Li)p are given (see fig. 8) which can be connected to the 6Li(p,p)6Li cross sections at approximately Elab(p)= 2 MeV.

Prof. Jacinto Liendo

I did not found the document Professor Jacinto

I think it is better using stopping power. There is data from NIST in the attached link

There is an interesting article about protons-Li6:

McCray_ja_1962 THE ELASTIC SCATTERING OF PROTONS FROM Li 6 nuclei

I did not found nothing about p+B11

http://www.nist.gov/pml/data/star/

http://thesis.library.caltech.edu/6620/

Is it what you need?

Actually there are the global optical potetnials fitting the elastic scattering data very well. They have some limitations on the target mass and energies, but one may use it for estimations at least... However in this case you have to apply special computer codes in order to solve the nucleus-nucleus scattering problem.

Dear Javier,

This is the complete reference. This paper cites other publications where you can find more data.

Prof. Jacinto, thank you for the effor, I have read the document unfortunately  it appear compounds and data units not valid for the simulations

Prof. Denikin, I have obtained the desired tables but it appear at the tables "y axis" the units: "DATA-CM, NO DIM", is the y axis data in barns or it is a relative unit?

Dear Javier,

all these data are the differential cross sections measured at specific scattering angle and ploted as ratio to the Rutherford cross section (therefore it is NO-DIM).

If you need I can send you the pdf-s with original papers (write me in [email protected]).
