His research concerned magnetism, in particular new magnetic structures and phenomena in first-order magnetic phase transitions, solid-state physics, reactor physics and correlation measuring techniques. He was the first to formulate the equation for the function that determines the time, space and energy distribution of neutrons in nuclear reactors (the Pál — Bell equation).
The L. Kossuth Prize (1965), the I. V. Kurchatov gold medal. President of the National Committee of Physicists. A foreign member of the USSR Academy of Sciences (1976).
