CoherentKS0Regeneration in Hydrogen and Deuterium from 3.5 to 10.5 GeV/c

Abstract

The amplitude and phase for coherent regeneration in hydrogen and deuterium have been measured for six momentum bins in the range 3.5-10.5 GeV/c. Over this region the phase, ${\varphi }_f$, is consistent with being constant and has the value - 60°±8° for hydrogen and - 46°±8° for deuterium. Power-law fits of the form ${p_{\mathrm{lab}}}^n$ for the amplitudes when combined with other data give $n=-0.60\mathrm{}\pm 0.02$ for hydrogen and $n=-0.52\mathrm{}\pm 0.02$ for deuterium.
