It is very difficult to theoretically predict the fission barrier and binding energy, however, it has confirmed that by adjusting the "Pairing Strength", values close to these experimental values can be reproduced relatively easily, and the physical quantities for evaluating the pairing strength, "pairing moment of inertia", can also reproduce values relatively close to the experimental velues to show their validity. Therefore, in our presentation, the inner fission barrier, binding energy, and pairing moment of inertia are calculated using Relativistic Mean Field Theory and BCS model. The pairing strength that minimizes the sum of these relative mean square errors is obtained using Gausse Process Regression. Now that we have verified the effectiveness, we will report on those results.
