We predict an increase in neutron emission for <sup>54</sup>Ca due to the abrupt decrease in neutron separation energy around t=0.4MeV. Since the drop in the separation energy is closely associated with the structural changes in the rotating nuclei, relative increase in neutron emission probability around certain values of temperature may be construed as evidence for the shape transition. Such effects are not obtained for <sup>40,48,52</sup>Ca isotopes. hence this statistical study reveals the higher stability of magic nature of <sup>52</sup>Ca than <sup>54</sup>Ca, against temperature.</p> ER -
