Da. Roberts et al., UNUSUAL ENERGY-DEPENDENCE OF THE TOTAL NUCLEAR-REACTION CROSS-SECTIONFOR A SECONDARY ISOMERIC NUCLEAR BEAM (F-18(M), J(PI)=5(+), E(X)=1.1 MEV), Nuclear physics. A, 588(1), 1995, pp. 247-252
A primary O-17 beam has been used to produce a 22.3 MeV/nucleon F-18(m
) isomeric secondary beam via a single nucleon transfer reaction on a
carbon target. The total nuclear reaction cross sections for F-18(m) a
nd F-18(g.s.) in silicon were measured in a stack of seven silicon sol
id-state detectors. The cross section for F-18(m) exhibits some unusua
l features at low energy not seen for F-18(g.s.) or other ions.
