Two aspects of heavy ion channeling are presented. The first aspect is
related to the fact that channeled ions interact only with the most l
oosely bound target electrons. One can take benefit of this feature to
study processes such as radiative electron capture (REC) and resonant
transfer and excitation (RTE) in a dense quasi-free electron gas. The
experimental work, performed at GANIL, devoted to these two processes
is described. A possible extension to Nuclear RTE or NEEC (nuclear ex
citation by electron capture) studies is also described. The second as
pect discussed is related to the periodicity of the potential experien
ced by channeled ions. We show that in a well chosen case this could l
ead to a significant and detectable coherent excitation of the project
ile nucleus.
