Spectropolarimetric titrimetry is a new analytical technique first described by KXRSC~NER ASD BHATNAGAR 1 in X963. A photoelectric polarimeter is used to monitor the change in optical rotation of a solution upon the addition of titrant. A recognizable change in optical rotation of the solution must

โฆ Synopsis
We describe a method for calibration of a lead-glass calorimeter that does not require a beam of known energy. The technique was used to calibrate the RADPHI lead-glass calorimeter at Jefferson Lab. The technique described can be applied to any segmented electromagnetic calorimeter capable of detecting all-photon decays of mesons, for example, p 0 ! 2g, Z ! 2g or o ! p 0 g. We also demonstrate how the measured 2g mass width of the p 0 and Z mesons can be unfolded to extract the single-shower energy and position resolution functions of the calorimeter.
