Dear Pierre,
Thank you for your important questions, here are the answers:
1- the Ni powder I utilized were pure Ni, no copper . At the end of the
operations in the reactor the percentage of copper was integrally bound to the
amount of energy produced. A charge which has worked for 6 monthes, 24 hours
per
day, at the end had a percentage of Cu superior to 30%
2- About the Ni isotopes: the isotopes after the operations were substantially
changed in percentage. We are preparing a campaign of analysys with a Secondary
Ions Mass Spectrometer at the University of Padua (Italy), at the end of which
the data will be published on the Journal Of Nuclear Physics.
Warm Regards,
Andrea
That is a lot of ash.
