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 GRIGOREV60) 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.) /// GRIGOREV57 [E. L. GRIGORIEV,SOVIET PHYSICS JETP 4,10(1957).] -- PI+ P DCS AT 427 MEV/C FROM 427 ELASTIC EVENTS IN EMULSION AT INP. DATA GIVEN GRAPHICALLY. /// MUKHIN56 [A. I. MUKHIN,1ST IC ON HE ACCELERATORS,GENEVA,V2,P204,1956] -- CONFERENCE PAPER ON GRIGOREV57 AND MUKHIN57(SEE MUKHIN57 EXPT). A TABLE OF THE GRIGOREV57 DATA IS GIVEN. /// MITIN57 [N. A. MITIN,SOVIET PHYSICS JETP 5,378(1957).] -- PI+ P DCS AT 480 MEV/C FROM 218 ELASTIC EVENTS IN EMULSION AT JINR. /// GRIGOREV60 [E. L. GRIGORIEV,SOVIET PHYSICS JETP 10,1123(1960).] -- PI+ P DCS AT 511 MEV/C FROM 167 ELASTIC EVENTS IN EMULSION AT JINR. /// GRIGOR60P [E. L. GRIGORIEV,SOVIET PHYSICS JETP 10,295(1960).] -- PI+ P POL AT 424 MEV/C AND THETA=140 DEG FROM 545 ELASTIC RESCATTERING EVENTS AT INP. PIONS WERE SCATTERED IN LIQUID HYDROGEN TARGET AND RECOIL PROTONS SCATTERED IN EMULSION. /// COMMENTS FROM LOVELACE71 COMPILATION OF THESE DATA -- LOVELACE71 PUTS THE DCS DATA IN A SPECIAL SECTION RESERVED FOR EXPERIMENTS THAT DISAGREE SERIOUSLY WITH OTHERS. /// COMMENTS ON MODIFICATIONS TO LOVELACE71 COMPILATION BY KELLY -- THE RENORMALIZATION CORRECTIONS GIVEN WITH THE LOVELACE71 VERSION OF THE DCS DATA (WHICH WAS APPARENTLY TAKEN FROM THE ORIGINAL RUSSIAN JOURNALS) ARE INCORRECT (WRONG SIGN AT ALL 3 MOMENTA,WRONG MAGNITUDE AT ONE). THE FORWARD POINTS DISAGREE WITH THE PUBLISHED VALUES EVEN WHEN THIS IS CORRECTED.. DATA ARE UNNORMALIZED OR NORMALIZED TO OTHER DATA.
