Table 1 Estimated energy loss (Equation 8) for a photoemitted electron as a function of its velocity

From: Dynamic screening of a localized hole during photoemission from a metal cluster

	N= 20	*υ =* 1 a.u.	*υ =* 1.5 a.u.	*υ =* 2.5 a.u.
E_loss, a.u.	Without hole	0.60	0.44	0.22
	With hole	0.37	0.30	0.16
Δ E_loss , a.u.		0.23	0.14	0.06

The electron is assumed to follow a trajectory with constant velocity. The difference in energy loss Δ E_loss for the case of absence and presence of a hole in the center of the cluster is also given.
