The Hamiltonian of two interacting spin-1/2 particles is \(H = \dfrac{A}{\hbar^2}\vec{S}_1\cdot\vec{S}_2\), where \(\vec{S}_1\) and \(\vec{S}_2\) are the spin angular momenta of particles 1 and 2, respectively. Here, \(A = 10.56\) eV. The energy in eV required to induce an excitation from the ground state to the excited state (rounded off to two decimal places) is ______
