“…Hill and Wheeler 1 set forth a qualitative picture in a first attempt to explain early experiments on photofission 2 and neutron-induced fission. 3 At the 1955 Geneva Conference Bohr 4 presented a detailed model relating angular distributions of the…”

Theoretical Analysis of Experimental Data on the Angular Anisotropy of Fragments of Nuclear Fission Induced by Neutrons at Energies of up to 200 MeV

“…ZN K e α The results are presented in Fig. 2 along with the experimental values of anisotropy we obtained in [8], and ones measured earlier for energies of up to 20 MeV [20][21][22][23][24][25][26].…”

“…It was shown that the model can be used to obtain new information about reactions at intermediate energies and the fission process. 1) from [20], (2) from [21], (3) from [22], (4) from [23], (5) from [24], ( 6) from [25], (7) from [26], and ( 8) from [8]. The dashed, solid, and dotted lines correspond to angular anisotropy calculated with parameters of 22, 17, and 12 keV, respectively.…”

Angular distributions and anisotropy of fission fragments from neutron-induced fission of239Pu,237Np, andnatPb in energy range 1–200 MeV

“…The average error of our measurements for 239 Pu and 237 Np is 1-3%, and for nat Pb -3-14% in the entire investigated neutron energy range. On the same figures for 239 Pu and 237 Np, the results of previous measurements of this anisotropy ( 239 Pu: [10-13, 15-18] and 237 Np: [12,13,15,16,[19][20][21]) included in the EXFOR database are shown. Despite the fact that there are some differences between our data and the results of these earlier works, it can be said that there is generally a satisfactory agreement, especially if we take into account the existing discrepancy between the archival data sets.…”
