No. It must reach the minimum threshold energy. Since its only half, there isn't enough energy for the electron to jump to the 2s energy level.

Side note: An electron can only jump between energy level if the minimum energy is met. If the energy of the photon does not meet this energy level and is below, the electron will not jump to the new level.
