TITLE Zero degree cross section for the reaction C080700100009
14C(p,n)14N(2.31), 14N(3.95) at 200, 300 and 450 MeV C080700100010
FACILITY (MESON,1CANTMF) C080700100011
SAMPLE Elemental carbon enriched to 89% 14C contained in C080700100012
natural nickel can. Total carbon thickness 170 C080700100013
mg/cm2. C080700100014
DETECTOR (MWPC) C080700100015
MONITOR (3-LI-6(P,N)4-BE-6,PAR,DA) Cross section assumed C080700100016
the same for all 3 bombarding energies. C080700100017

ANALYSIS Count rates under peaks summed and measurements of C080700100021
ratio of cross section to the 2 states were used C080700100022
to obtain the seperate cross sections. C080700100023
CORRECTION Corrected for detector efficiencies and dead time. C080700100024
ERR-ANALYS (DATA-ERR) Uncertainty given include uncertainties C080700100025
due to: C080700100026
. counting statistics, C080700100027
. beam integration (about 4%), C080700100028
. cross section ratios of 2 levels (4% at 200 MeV, C080700100029
7% at 300 MeV, 16% at 450 MeV). C080700100030
Additional systematic uncertainties in 7Li(p,n) cross C080700100031
section (7%), and 14C target thickness (9%). C080700100032
