The phrase "at half intensity" is correct and usable in written English.
You can use it when describing the level of power, brightness, or force of something, often in contexts like lighting, sound, or physical exertion.
Example: "The stage lights were set at half intensity to create a more intimate atmosphere for the performance."
Alternatives: "at reduced intensity" or "at moderate intensity."
This causes the light connected to the dimmer to glow at half intensity.
For example, if the dimmer is set at half intensity, it conducts for half its cycle and does not conduct for the other half.
The bandwidth at half intensity at 1721 cm−1 was directly related to the amount of the total rigid phase and confirmed by the variation of the heat capacity increase at the glass transition temperature.
The bandwidth at half intensity at 1721 cm−1 in the Raman spectrum varied between 32 cm−1 for the complete amorphous phase and 7 cm−1 for the total rigid phase, the sum of the rigid amorphous and crystalline phase.
The extrapolation of the bandwidth at half intensity at 1721 cm−1 to the value of zero, corresponding to the complete crystalline phase, gave a melting enthalpy of 196 J/g and the corresponding density of the crystalline phase was 1.4390 g/cm3.
The crystallite size (P) of Dy doped samples were roughly estimated from the broadening of a few XRD peaks (in a wide 2θ range) using the Scherrer's equation [19], (P = Klambda (beta_{{frac{1}{2}}} cos theta_{text{hkl}} )) (where K = constant = 0.89, λ = 1.5405 Å and β 1/2 = peak width of the reflection at half intensity).
The orientation of samples was also characterized by measuring the full width at the half intensity maximum of small angle X-ray scattering intensity circle profiles and showed good correlation with modulus measurements.
The NUV-vis light was produced by a light-emitting diode (LED) array OD-20499) (Opto Diode Corp, sourced from AP Technologies, Bath, UK) with a central wavelength of 395 ± 5 nm, a bandwidth of 12 nm full-width at half maximum (FWHM), and a half intensity beam angle of 30° [ 40].
The reaction of an MgCl2-supported Ziegler catalyst with alkylaluminium was observed to induce a chemical shift to lower binding energy and a broadening of the full width at half maximum intensity (FWHM), depending upon the kind of alkylaluminium.
However, the G peak position decreased from 1588.2 to 1582.2 cm−1, the width of the G band at half maximum intensity decreased from 46.3 to 28.9 and that of D band from 46.9 to 36.7 cm−1 from core to skin after HTT at 2500 °C.
In this formula, K (Scherrer's constant) is 0.89 for TiO2 [17], β is full width at half maximum intensity and θ is the angle.
