“…In this configuration we detect r/mesons produced in a kinetic energy interval ranging from 30 to 100 MeV at an angle varying from 0 ~ to 40 ~ in the laboratory as shown in [ 1 ]. The doubly differential cross sections for the pA ~rIX reaction at Tp = 0.9 GeV are presented in Fig.…”

Subthreshold K? production in pion-nucleus reactions

“…in proton-nucleus reactions at the energies below the corresponding thresholds for the free nucleon-nucleon interactions has arisen during the last years both experimentally and theoretically [1][2][3][4][5][6][7][8][9][10][11]. The reason of this interest is to obtain information about nuclear phenomena which are intrinsic to the nuclei singly (such as Fermi motion, high-momentum components of the nuclear wave function, clusters of nucleons or quarks), and about those, which characterize the collision itself (for example, the production of particles via secondary processes).…”
