Fabrication of the ⁸²Se isotopic target on ¹⁹⁷Au backing

Heavy-ion fusion evaporation reactions are used in nuclear structure studies to examine the quantum states of nuclei by populating the high spin states. The isotopically enriched ⁸²Se target on ¹⁹⁷Au backing were fabricated by the resistive heating method using the Molybdenum boat in the diffusion pump based coating unit at the Department of Physics & Astrophysics, University of Delhi, New Delhi, India. The description of the setup used and procedure of fabrication is given in the article. The thickness of fabricated target was measured using an optical profilometers. The ⁸²Se (⁷Li,xn) reaction was performed using the fabricated target at 28, 33 and 36 MeV beams. The experiment was performed at the Indian National Gamma Array (INGA) facility at the IUAC, New Delhi with the above prepared target using the ⁷Li beam having energy 28, 33 and 36 MeV. The projection spectrum at 33 MeV observed from the ⁷Li + ⁸²Se reaction is shown in the article. The characterization of the material to find the purity of sample is in progress
