Query: Activation cross-sections of longer lived products of proton induced
  nuclear reactions on cobalt up to 70 MeV   As a part of our series of studies on deuteron induced reaction on various
target materials excitation functions on natural cobalt have been measured by
using stacked-foil technique. In these measurements 51Cr, 55;56;57;58Co, 51Cr,
52;54;56Mn and 56;57Ni radioisotopes have been identified. For the above
isotopes the excitation functions were determined and compared with the
literature data and with the results of EMPIRE and TALYS calculations taken
from the TENDL 2011 library. The agreement with previous measurements was
acceptable and we could also determine new cross-section data.
