Abstract
The formation of a deeply-bound K – pp state by the 3He(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 \(\theta_n = 0^{\circ}\) 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.
