1：Experimental Design and Method Selection:

The study designed experiments to test two new methods for processing interlaced overlap peaks in c-ray spectra: a symmetric conversion method based on Gaussian distribution for small overlaps and an energy average method for significant overlaps from the same reaction. The rationale was to overcome the inability of existing HPGe multichannel spectrum software to provide reliable net counts in such cases.

2：Sample Selection and Data Sources:

Samples included natural tungsten foils (purity 99.99%, thickness 2.0 mm, diameter 2.0 cm) irradiated with 14 MeV neutrons from a T(d,n)4He reaction at the K-400 Neutron Generator. Data were collected using a calibrated HPGe detector, with decay characteristics and abundances referenced from standard nuclear data sources (e.g., NuDat 2.6, Table of Isotopes).

4. Experimental Procedures and Operational Workflow: Samples were irradiated at specific angles and distances from the neutron source, monitored for neutron flux using alpha-particles. After irradiation, c-activities were measured with the HPGe detector. Spectra were analyzed using the proposed methods: for small overlaps, the symmetric conversion method was applied to calculate net counts; for significant overlaps, the energy average method was used. Background counts were subtracted using predefined methods, and cross sections were calculated relative to a monitor reaction (93Nb(n,2n)92mNb).

6：Data Analysis Methods:

Data analysis involved calculating net peak counts using the symmetric conversion and energy average methods. Cross sections were computed using an equation from literature, with statistical uncertainties considered. Results were compared with literature values and evaluated nuclear data (JEFF-3.3, JENDL-4.0) to validate reliability.
