The fragments were detected with low-pressure positionsensitive multi-wire proportional counter and the gamma-rays with a plastic scintillators. The time-of-flight method is used to discriminate prompt neutrons and promptγ-rays of fission. From the measured angular distributions with respect to the directionof the selected fragments, the value of the laboratory anisotropy has been found to be15 $\%$ in comparison to the value obtained in the perpendicular direction. The measurements indicate the existence of a significant anisotropy of emission of the γ-rays in theemitting-fragment system, suggesting the presence of significant angular momenta ofthe fragments correlated with the fission axis, which also lead to an enhanced emissionof the γ-rays. Moreover, the article includes a new technique for measuring and correcting the obtained angular distribution, in the case of when plastic scintillators havedifferent threshold levels for detection of γ-rays.}, cin = {JCNS-2 / JCNS-3 / JCNS-4 / JARA-FIT / MLZ / JCNS-FRM-II / PGI-4}, ddc = {530}, cid = {I:(DE-Juel1)JCNS-2-20110106 / I:(DE-Juel1)JCNS-3-20170926 / I:(DE-Juel1)JCNS-4-20201012 / $I:(DE-82)080009_20140620$ / I:(DE-588b)4597118-3 / I:(DE-Juel1)JCNS-FRM-II-20110218 / I:(DE-Juel1)PGI-4-20110106}, pnm = {6G4 - Jülich Centre for Neutron Research (JCNS) (FZJ) (POF4-6G4)}, pid = {G:(DE-HGF)POF4-6G4}, experiment = {EXP:(DE-MLZ)POLI-HEIDI-20140101}, typ = {PUB:(DE-HGF)16}, doi = {10.34734/FZJ-2023-04595}, url = {https://juser.fz-juelich.de/record/1018151}, }
