Contact angle and the

decay time constant for surface charge decay of virgin and gamma irradiated samples.

The start time in the rise time calculation and end time in the

decay time calculation are based on the difference in adjacent speed values.

Actually, the light-yield values of common scintillators are evaluated by pulse height analysis, and with the present technologies available to determine the scintillation light yield of slow materials that have a scintillation

decay time longer than 100 ys is difficult.

It reached the 65000 photons/MeV with two

decay time constants of 93.5 ns and 615 ns, the relative intensities of which is 40.2% and 50.8%, respectively.

In air atmosphere, there is a constant flux of oxygen molecules which contributes to shorter

decay times as compared to other atmospheres.

For example, when the probes particles are immersed in a Newtonian fluid, the autocorrelation function of the intensity minus one decays exponentially and its

decay time is proportional to the medium viscosity; see (2) and (4).

decay time constant [t.sub.D].

In order to convert the measured

decay time to temperature values, a calibration curve for the thermographic phosphor employed is needed.

where A1 and A2 are the fraction of the fast and slow decay components, respectively, As is the steady-state current, and ?1 and ?2 are the fast and slow

decay time constants, respectively.

This fact has to be taken into account in a complete explanation for the

decay time distribution in this process.

The second invariant of form (5) is a product of the AE signal amplitude A and the value of

decay time [t.sub.decay].
