http://en.wikipedia.org/wiki/Inelastic_collision An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved. http://journals.aps.org/archive/abstract/10.1103/PhysRev.114.1584 nonelastic (total minus elastic)...

Commercial-type setup like this one connect a current meter with the right (green) side of the target body. A colleague explains to me that once the proton enter the target, by the law of charge conservation, positive electricity carried by the proton must flows through the current meter if it's...

I'm sorry not that the diagram is not clear. A typical radioisotope target system is like: https://www.dropbox.com/s/sshbew3bqrwtjwh/measure.jpg The proton beam coming from the left, passing through foil, then hits the water. A control run without the target is a good way, but the flux...

https://www.dropbox.com/s/pwkgce1d9rcj3ev/target.JPG https://www.dropbox.com/s/pwkgce1d9rcj3ev/target.JPG The beam is fully stopped in the target material (light blue) before reaching x. I'm curious is this how the cyclotron that produce medical isotope measure beam current. Please advise me...

The proton current in cyclotron are normally measured by Faraday Cup. However, I do not understand that if there is target material for the proton beam. Proton is fully stopped in the target material, for example, water. How the current is measured if it did not hit anything else?

The equation of radionuclide production is as follow dN/dt = k - λN All my textbook assumes that k is a constant vale. http://jol.liljenzin.se/KAPITEL/CH15NY3.PDF for the equation to be valid, (iii) the flux is not decreased ... . .. Corrections must then be introduced. Please...

Please let me rephrase my the question. I'm looking for the cross section of 18O(p,n)18F in the ENDF file of TENDL provided in the link: p + 18O : (p,n) ftp://ftp.nrg.eu/pub/www/talys/tendl2013/proton_file/O/018/xs/xs100000.tot 18O(p,x)18F : Production of 18F...

I got an reply of the answer, it's in page 41 eq. 3.22 of talys manual.

I'm trying to find specific reaction cross section 18O(p,n)18F in proton + O-18 TENDL (ENDF format). # p + 18O : (p,n) Total # Q-value =-2.51902E+00 # E-threshold= 3.64964E+00 # # energies = 45 # E xs 1.000E+00 0.00000E+00...

I'm reading the cross setion of p + 18O Total neutron production ftp://ftp.nrg.eu/pub/www/talys/tendl2013/proton_html/O/ProtonO18xs.html # p + 18O Total neutron production # Q-value =-2.51902E+00 # # # energies = 45 # E xs...

I'm sorry for 9.1E9cm, should be 0.16E+10 cm , converting to 0.11 mbarns. Also, it should be hydrogen instead of proton. However, is there other resources to compare ?

The question arose to me when I do a simulation on FLUKA, there is inelastic scattering length 9.1E9 cm of proton-proton(H) in 10MeV. 9.1E9 cm which converting to 0.011mb. https://www.dropbox.com/s/gul3dibeqlgmmej/MeV10%20Material.JPG It is really small compare to other process or elastic...

Dear Forum ： I'm looking for proton-proton inelastic cross section in MeV. There are lots of results in GeV, TeV. But I can not find the results in MeV in ENDF nor TENDL. https://www-nds.iaea.org/exfor/endf.htm ftp://ftp.nrg.eu/pub/www/talys/tendl2011/proton_html/proton.html Please advise...

You are looking for theses from accelerator-based neutron source from BNCT ? You can google Kyoto,BNCT . http://accelconf.web.cern.ch/accelconf/Cyclotrons2010/papers/frm2cco04.pdf

Astronuc , thanks for your response. I select all of the 8 library to find proton interaction with O-16, but it seems that I can not even find 16O(p,a)13N out of it.
