TITLE=/CROSS SECTIONS FOR THE 26MG(P,N)26AL(GROUND,7.3E+5 YEAR) AND
26MG(P,N)26AL(METASTABLE,6.35 SEC) REACTIONS/;
PURPOSE=/WE REPORT THE RESULTS OF AN EXPERIMENTAL INVESTIGATION OF THE
CROSS SECTION FOR 26MG(P,N)26AL-M1 OVER THE RANGE OF PROTON
ENERGIES OF INTEREST IN NUCLEOSYNTHESIS. CALCULATIONS OF THE
CROSS SECTIONS FOR BOTH THE 26MG(P,N)26AL-M1 AND 26MG(P,N)26AL
REACTIONS ARE CALCULATED, ACCORDING TO THE STATISTICAL THEORY
OF NUCLEAR REACTIONS FOLLOWING THE PRESCRIPTION OF WOOSLEY ET
AL. WHO HAVE PRODUCED EXTENSIVE TABLES OF THERMONUCLEAR
REACTION RATE DATA INCLUDING CROSS SECTIONS FOR INTERMEDIATE
MASS NUCLEI. BY COMPARISON OF THE THEORETICAL CROSS SECTIONS
WITH OUR EXPERIMENTAL RESULTS AS WELL AS MEASUREMENTS AT
6 AND 8MEV FOR 26MG(P,N)26AL BY FURUKAWA ET AL.,
NUCL.PHYS.A174,539(1971)./;
