In this paper, the recently developed technique of measuring diffusion-relaxation distribution functions in grossly inhomogeneous fields was applied to the characterization of bulk fluids. The measurements were conducted in a static stray field of a

Correlations between nuclear magnetic resonance based relaxation and diffusion-diffraction measurements in fluid-saturated isolated pores with relaxing surfaces are investigated. These correlations can be measured in two-dimensional experiments using

The Driven-Equilibrium Carr-Purcell Meiboom-Gill (DECPMG) pulse sequence is a rapid method for obtaining the average ratio of longitudinal to transverse relaxation times (T(1)/T(2)) as a function of T(2). Since this is a one-dimensional experiment, t

Using a cryogenic hydrogen maser, suitably modified to have electronic control of both the resonance frequency and the quality factor of the external cavity, we have measured a number of spin-exchange parameters for an atomic-hydrogen (H) gas at a te

Hydrogen masers are presently the most stable atomic clocks for averaging times τ between 1 s and 1000 s. With the best conventional devices, frequency fluctuations of less than 10−15 for averaging times of about 1 hour are measured [1]. In 1978 i

We report on the design and initial testing of a new type of hydrogen maser, operated at dilution refrigerator temperatures, in which H atoms circulate back and forth between a microwave-pumped state selector and the maser cavity. Other novel design

Conventional hydrogen masers are the most stable of all atomic clocks with stabilities Δf/f of better than 10-15 for measuring times τ of 103 sec. A new generation of cryogenic hydrogen masers has the potential to improve this figure by 2 to 3 orde
