A. Angelopoulos et al., MEASUREMENT OF THE NEUTRAL KAON REGENERATION AMPLITUDE IN CARBON AT MOMENTA BELOW 1 GEV C/, Physics letters. Section B, 413(3-4), 1997, pp. 422-430
The neutral kaon regeneration amplitude in carbon at momenta between 2
50 and 750 MeV/c was determined by measuring the interference of inher
ent and coherently regenerated K-S amplitudes. This interference appea
rs in the rates of initially pure (tagged) K-0 and (K) over bar(0) dec
aying to pi(+)pi(-) after crossing a carbon absorber. (C) 1997 Publish
