THE C$sup 12$(p,pn)C$sup 11$ AND Al$sup 27$(p,3pn)Na$sup 24$ CROSS-SECTIONS AT 591 MEV

Journal Article · · Nuclear Phys.
The absolute cross sections of the reactions C/sup 12/(p,pn)C/sup 11/ and Al/sup 27/ (p,3pn)Na/sup 24/ were measured by exposing polythene and aluminum targets to the 591-Mev external proton beam of the CERN synchrocyclotron. The proton flux was measured with a secondary emission chamber, calibrated by a counter telescope technique. The C/sup 11/ and Na/sup 24/ activity, induced in the targets, was determined by conventional counting methods, using calibrated Na/ sup 22/ and Na/sup 24/ sources as primary standards. The measured cross sections are 29.9 plus or minus 1.5 mb and 11.0 plus or minus 0.5 mb for the reactions C/sup 12/(p,pn)C/sup 11/ and Al/sup 27/(p,3pn)Na/sup 24/, respectively. (auth)
