The production yields ofneutron-deficient nuclei ¹²⁷Cs and ¹²⁹Cs have been measured in the reaction of ¹¹B with ^natSn target using heavy-ion-induced complete fusion reaction. The experimentally determined production yields are compared with the statistical model predictions and are found to be in good agreement. The yields from heavy-ion fusion reactions are compared with that produced in spallation reactions. The present study is carried out as a part of our program ofmeasurement ofground state properties ofradioactive nuclei by laser spectroscopy.
