Summary
The lifetime of the 1.701 MeV level in18F has been measured with the DSAM by means of the inverse3He(18O, p) reaction at 15, 18 and 21 MeV incident energy, on Ta and Al backings. Dependence of the extracted values on incident energy and stopping material has been found. It is shown that both effects can be explained as due to cascade feeding from higher levels.
