Precession measurements following Coulomb excitation with oxygen ions: (III). Gyromagnetic ratios of rotational states in W isotopes

Abstract

A measurement of the g-factor of the 5 2 - state at 99 keV in 183W is reported. Measurements are also described which make use of internal magnetic fields in saturated ferromagnetics. The value and sign of the internal fields acting on a tungsten nucleus in nickel, cobalt and iron have been determined with the aid of these fields. Precession measurements have been carried out for the 4 + levels in 182W, 184W and 186W. It is also established through the internal consistency of the results that the internal fields are set up during a time shorter than 5 × 10 −11 sec.
