摘要：
The formation of a deeply-bound K(-)pp state by the He-3(in-flight K-, n) reaction is investigated theoretically in a distorted-wave impulse approximation using the Green's function method. The expected inclusive and semi-exclusive spectra at p(K-) = 1.0 GeV/c and theta(n) = 0 degrees are calculated for the forthcoming J-PARC E15 experiment. We discuss these spectra with some K--"pp" optical potentials, taking into account the energy-dependence of the imaginary part of the potentials by a phase space suppression factor.
