“…Incidentally, it is well known that the energy losses of the particles incident on a target foil depend on their angle of emergence due to the impact parameter dependence of the energy loss [11][12][13][14][15][16][17][18]. Judging from the close relation between the energy loss and the SE emission [4], it is readily predictable that the SE emission also depends on the impact parameter or, in other words, the scattering angle of the incident ions.…”

The statistical distributions of the secondary electrons (SEs) emitted forward and backward from a thin carbon foil have been measured simultaneously, in coincidence with foil-transmitted protons of 1.0 and 2.5 MeV, as a function of the angle of emergence, θ em , of the protons. Irrespective of the incident energy, the measured SE yields increase with increasing angle of emergence in both the forward and the backward directions. As for the forward-backward correlation of the SE emission, the forward-and backward-emitted SE yields induced by 2.5 MeV protons increase gradually with increasing number of SEs emitted in the opposite directions. This positive correlation becomes slightly more pronounced with increasing angle of emergence. On the other hand, for 1.0 MeV, a positive correlation observed at θ em = 0 mrad changes to a negative one at θ em = 1.0 and 2.0 mrad.
