Abstract
This paper presents results obtained by the NA48/2 experiment at CERN SPS. Data samples of 1.24 x 10(5) K(+/-) -> pi(+/-)pi(0)gamma, 7146 K(+/-) -> pi(+/-)e(+)e(-) 1164 K(+/-) -> pi(+/-)gamma gamma and 120 K(+/-) -> pi(+/-)e(+)e(-)gamma decays (this last one observed for the first time) have been collected with small background, allowing precise measurements of branching fractions and other characteristics of these rare kaon decays.
