Study of nuclear quadrupole interactions in different environments of decaying atoms of 75Se by sum peak method.
The sum peak intensity I400 (279 + 121 keV) relative to its singles peak intensity I279 or I121 has been determined in various environments of 75Se by gamma-gamma summing technique in a single HPGe detector. The change in intensity has been used to determine nuclear quadrupole interaction frequencies and electric field gradient components in different environments, e.g. Se-glycerol, Se-hydrochloric acid (HCl), Se-perchloric acid (HClO4), Se-blood samples with and without anti-coagulant, Se-alanine and Se-cysteine at different pH values. The electric field gradient is found to vary with chemical complex formation.
