Çekmece Nuclear Research Center.http://kurumsalarsiv.tenmak.gov.tr/handle/20.500.12878/616TENMAK D.N.. 10291The curves for isotopic and isotonic fission yields are calculated and shown to be the Weierstrass transforms of the isoboaric yield curve. The Well-known mass asymmetry of the fission is associated with asymmetry in charge and in neutron contents. There are "forbidden" zones at 44 Z 48 and at 64 N 78, where formation probabilities are extremely low. The distribution of the number of neutrons of the fission fragments is much narrower than what would be expected on the basis of the variation ranges for Z and N. The ambiguity existing about whether the fragments of a pair are meant to complement before or after prompt neutron boil-off is removed, and Glendenin's treatment is confirmed. There are indications, which are in full agreement with the properties of Wahl's empirical Z(p) function, that the proton closed shell contribution (if any) to the fine structure observed in the isobaric yield curve may be larger than the contribution of the neutron closed shell. The isotopic yields of the known nuclides are significantly smaller than the yields defined by the full theoretical curves for Z = 38, 39, 40, 41, 52, and 57, indicating that new isotopes of Sr, Y, Zr, Nb, Te, and La are still to be identified as primary fission products from the thermal neutron fission of U(235).enginfo:eu-repo/semantics/openAccessNuclear fissionNükleer fisyonreport
