Study of the reactions and near the coulomb barrier

摘要: Abstract The vector analyzing power and differential cross section have been measured at a deuteron energy of 12.3 MeV for 208 Pb ( d , p ) transitions to seven states 209 E x = 0.0, 0.79, 1.42, 1.56, 2.01 2.47+2.51 MeV, t three 207 0.57 0.89 MeV), . Two optical model potentials were obtained from analysis the elastic scattering measurements, used in DWBA present transfer-reaction results previous 0 sensitivity nuclear interior is investigated. relative importance Coulomb distortions discussed. sign given l n depends on j Q -value both d, d,t reactions. -dependence invalidates simple rule proposed by Griffith Roman relate predominant iT 11 Comparison measurements predictions θ allows unambiguous determination all except All spins determined work confirm assignments. powers are observed be similar angular dependence but opposite angles. reversal reflects differences proton triton waves.
