Nickel foils were placed in front of and behind the Au+Sand, the blank crucible, and the gold foil. Nickel foils were also place in front of and behind the crucible with the Barium Oxide.

lines are observed near, 238, 511, 578, 604, 903, 1264, 1362 keV

Naturally occurring Isotopes of Nickel are

Ni-58 ( 68.077% ) Ni-60 ( 26.223% ) Ni-61 ( 1.140% ) Ni-62 ( 3.634% ) Ni-64 ( 0.926% )


Neutron knockout

Ni-58 ->Ni-57 has the following lines in order of decreasing intensity: 511, 1377, 127 , 1919 half life = 35.6 hours

Ni-60 -> Ni-59 : no high intensity lines above 100 keV, half life 7e4 years

Proton knockout

Ni-58-> Co-57 : 122,136, half life 271.74 days

N-P knockout

Ni-58->Co-56 :847, 1238, 511, 2599, 1771, 1038, half life = 77 days


Extracting Photon flux using Nickel Foil

The two reactions below can be used to extrapolate the photon flux
