Vor 6 Stunden · A few years later, American physicist Isidor Isaac Rabi, working at Columbia University, demonstrated NMR phenomena for the first time by using radio frequency (RF) fields to induce transitions between the nuclear energy levels of a molecular beam. In 1938, Rabi’s team observed the decrease in signal intensity of a lithium chloride (LiCl) beam at the detector under a resonance condition ...
Vor 3 Tagen · During the 1930s, the American physicist Isidor Isaac Rabi built equipment for atomic beam magnetic resonance frequency clocks. The accuracy of mechanical, electromechanical and quartz clocks is reduced by temperature fluctuations.
Vor 2 Tagen · Many top scientists, as well as government and military figures, testified on Oppenheimer's behalf. Physicist Isidor Isaac Rabi said that the suspension of the security clearance was unnecessary: "he is a consultant, and if you don't want to consult the guy, you don't consult him, period."

Vor 4 Tagen · The effort to build a nuclear reactor in the American northeast was fostered largely by physicists Isidor Isaac Rabi and Norman Foster Ramsey Jr., who during the war witnessed many of their colleagues at Columbia University leave for new remote research sites following the departure of the Manhattan Project from its campus.

Vor einem Tag · Isidor Isaac Rabi, an American physicist of Polish descent, was awarded the Nobel Prize in Physics for developing a method for measuring the magnetic moments, or the spin and magnetic properties of atomic nuclei. This measurement methodology served as a foundation for further research on atomic beams, which in turn led to the ...
