    Area of Science:

    • Nuclear Physics
    • Spectroscopy
    • Data Compression

    Context:

    • Gamma-ray spectroscopy is crucial for nuclear applications.
    • Spectral data analysis often requires significant storage and processing power.
    • Existing methods for spectral data representation can be computationally intensive.

    Purpose:

    • To propose a novel method for representing gamma-ray response spectra.
    • To compress spectral data efficiently using Fourier series.
    • To evaluate the effectiveness of the proposed method for NaI detector spectral libraries.

    Summary:

    • A method using Fourier series representation is developed for gamma-ray response spectra.
    • Response spectra are modeled as a superposition of low-frequency sine and cosine waves.
    • Fast Fourier Transform (FFT) is employed to obtain spectral coefficients, reducing parameters by about half with minimal fitting error.

    Impact:

    • Enables significant reduction in spectral data size, facilitating storage and analysis.
    • Demonstrates practical applicability in analyzing gamma-ray spectra from NaI detectors.
    • Offers a more efficient approach to spectral data processing in nuclear science.
