Analysis of multiplicity gated high energy gamma spectra for extracting giant dipole resonance parameters

The procedures adopted in analyzing the experimental multiplicity gated high energy gamma spectra for extracting the angular momentum dependent giant dipole resonance parameters have been discussed. A Monte Carlo based statistical model analysis is necessary for an accurate extraction of the parameters. A method is devised to use the code CASCADE for making an equivalent Monte Carlo calculation of the multiplicity gated high energy gamma spectra. A practical approach for a fast search of the resonance parameters using this equivalent Monte Carlo analysis is suggested and the accuracy of such procedure is demonstrated.
