"Table 16" of "eta and eta-prime Production near Thresholds and Backward Charge-Exchange Differential Cross Section in pi--p Reactions"

THE FOLLOWING COMMENTS ARE TAKEN FROM THE PI N COMPILATION OF R.L. KELLY. THEY ARE THAT COMPILATION& apos;S COMPLETE SET OF COMMENTS FOR PAPERS RELATED TO THE SAME EXPERIMENT (DESIGNATED HYMAN68) AS THE CURRENT PAPER. (THE IDENTIFIER PRECEDING THE REFERENCE AND COMMENT FOR EACH PAPER IS FOR CROSS-REFERENCING WITHIN THESE COMMENTS ONLY AND DOES NOT NECESSARILY AGREE WITH THE SHORT CODE USED ELSEWHERE IN THE PRESENT COMPILATION.) /// HYMAN68 [E. HYMAN,PR 165,1437(1968).] -- CEX DCS NEAR 180 DEGREES AT 720,750,780,AND 805 MEV/C. DONE AT COSMOTRON USING NEUTRON TIME OF FLIGHT (WITH ABOUT 15 PCT NEUTRON DETECTION EFFICIENCY) AND CHARGED PARTICLE VETO COUNTERS SURROUNDING THE TARGET. THIS WAS PRIMARILY AN ETA PRODUCTION EXPERIMENT WHICH ALSO PRODUCED CEX DATA. THE SAME NEUTRON DETECTION EFFICIENCY WAS USED FOR THE CEX NEUTRONS AS FOR THE ETA PRODUCTION NEUTRONS THOUGH IT IS STATED THAT THE EFFICIENCY MAY BE AS MUCH AS 25 PCT HIGHER FOR CEX. AT 720 AND 780 MEV/C THE DATA APPEAR TO BE SYSTEMATICALLY LARGER THAN THOSE OF CHIU67 BY AN AMOUNT OF ORDER 10 TO 20 PCT. THUS WE RECORD THE OVERALL NE AS UNKNOWN,BUT KEEP THE +/-15 PCT RELATIVE NE BETWEEN DIFFERENT NEUTRON COUNTERS GIVEN BY HYMAN68. /// COMMENTS ON MODIFICATIONS TO LOVELACE71 COMPILATION BY KELLY -- LOVELACE71 RECORDS AN OVERALL NE OF 7 PCT (THE SAME AS FOR ETA PRODUCTION) AND NO RELATIVE NE.. SYSTEMATIC ERROR CORRELATIONS TOO COMPLICATED TO ENCODE. SEE ORIGINAL PAPER FOR DETAILS.
