Ionel Solomon

Ionel Solomon (born 1929) is a French-Romanian physicist, Member of the French Academy of Sciences, CNRS Research Director, and Professor at the Polytechnic School in Paris.

Education

  • 1949-1951 PhD, Polytechnic School (École Polytechnique) in Paris

Major scientific contributions

Ionel Solomon made major contributions to the fields of: Nuclear Magnetic Resonance (NMR), Solid state physics, Semiconductors and Photovoltaics. In Nuclear Magnetic Resonance he derived fundamental equations that bear his name, and specify the nuclear spin-echo response and dipole-dipole interactions in solids (the Solomon equations).
