CAPTURE wIDTH OF 2-9 KEV RESONANCE SHOULD BE
MEASURED IN THREE DIFFERENT EXPERIMENTS. RESULTS
SHOULD COINCIDE WITHIN LIMITS OF 5-7 PERCENTo
IF HIGH RPI CAPTURE WIDTH CONFIRMED, ENERGY
DEPENDENCE OF CAPTURE CROSS SECTION SHOULD BE
MEASURED FROM THERMAL TO RESONANCE REGION TO
INVESTIGATE INTERFERENCE BETWEEN DIRECT AND
RESONANCE CAPTURE;
