O1741 1 20 For determination of production rates of Ca-41, samplesO1741 1 21 of high-purity Ni were irradiated isotopically with O1741 1 22 1600 MeV protons in cores of an artificial meteoroid O1741 1 23 made of iron, 99% purity.

O1741 1 28 (ASEP) O1741 1 29 DETECTOR (IOCH) Particle identification was made with a four- O1741 1 30 anode ionization chamber. O1741 1 31 ADD-RES The production rates of Ca-41 from Ni was obtained O1741 1 32 from the isotopic irradiation of an iron sphere with O1741 1 33 1600 MeV protons and reported in table 2.
