CEvNS detectors could provide new opportunities in nuclear physicsapplications if they can improve existing parameters such as neutrino detectorsize, portability, their sensitivity to a large range of reactor antineutrinoenergies, and resources required for operation. Thus, modelling theantineutrino spectrum is a crucial step to study the reactor antineutrinospectra and the CEvNS detector response. The first objective of this paper isto study the importance of fission product libraries in the construction ofantineutrino spectrum using the summation method and with various corrections.We have used ENDF/B-VIII and JEFF3.3 as our base data to model the spectrum. Wehave also included the TAGS data (pandemonium free) when such data isavailable. The isomeric transitions correction has the highest impact on theantineutrino spectra increasing the values 29% to 37% on an average in theenergy range of 0.5 MeV to 2 MeV. This correction also shows an increase of4.71% to 7.13% in the range of 0 to 2 MeV, with improving isomeric transitionsusing the TAGS data. Next, the spectra including the isomeric transitioncorrection using the Gross Theory causes reduction by 11.56 % to 69.46 % in therange of 6 to 8 MeV. The finite size, radiative, and weak magnetism correctionscause no more than 3.27% difference between the corrected and uncorrectedspectra. Our second objective is to calculate pulse height distributions of Geand Si based CEvNS sensors assuming a 20eV nuclear recoil threshold. In ourstudy, we have assumed a 100kg detector placed 10m away from the 1MW TRIGAreactor. Our results show that the detector response with corrected spectra fora natural Ge and Si detector are 44.25events/day and 7.99events/day. Thebiggest impact on the detector response is due to the isomeric transitioncorrection; with 37% difference between the corrected and uncorrected detectorresponse is observed.
