Cross sections of cumulative K exp + and K exp - -meson production in the 200-1000 MeV kinetic energy range at 90 deg, 120 deg, 168 deg (l.c.s.) are measured. The ranges of kinetic energies and emission angles mean that, according to the hypothesis of cum ...

Charged pion production induced by 201 MeV protons on Ni58 and Ni64 has been studied. The double differential cross sections have been measured over a wide angular range. Different behavior of the angular distribution is observed for low and high energy pions. The yield of positive pions shows a pronounced forward peaked component. The deduced total production yields are about the same for (p,π+) on both isotopes whereas that for (p64,π−) is twice as large as for (p58,π−).
MOMENTUM ACCEPTANCE OF SPECTROMETER = 2.5 PCT, AND TOTAL EFFICIENCY =0.8 +-0.05. THE TARGET THICKNESS WERE 42.7 +-0.2 AND 41. +-0.2 MG/(CM**2), ENRICHED TO 99.3 AND 98.2 PCT FOR NI58 AND NI64 RESPECTIVELY.
