M028300100018 COMMENT Angular distributions of photoneutrons from the M028300100019 Pb-207,208(g,n) reactions (ground state transitions) M028300100020 were measured at 11 angles between 40 degrees and M028300100021 140 degrees. The results are compared with M028300100022 calculations using a direct-semidirect model which M028300100023 involved an E1 and isoscalar E2 giant resonances. M028300100024 the results indicate that this model could explain M028300100025 only certain features of the data while most of M028300100026 the other features remain unexplained.
