O067400100010 SAMPLE (28-NI-58,ENR=0.9987) The high-current target consistedO067400100011 of a thin layer of 58-Ni deposited on a wedged O067400100012 copper block. O067400100013 Isotopic composition of enriched nickel target: O067400100014 58-Ni - 99.87+/-0.02%, O067400100015 60-Ni - 0.103%, O067400100016 61-Ni - 0.004%, O067400100017 62-Ni - 0.007%, O067400100018 64-Ni - 0.016%. O067400100019 Electrodeposited layers of 58-Ni of about 108 mu-m O067400100020 thickness are obtained. O067400100021 METHOD (SITA) O067400100022 (ACTIV) The proton beam current of about 10 mu-A.

O067400300004 COMMENT - By Authors - Due to the exceptionally high (p,2p) O067400300005 cross section, the major part of the 57-Co is formed O067400300006 directly and not via the decay of 57-Ni.
