“…Lately [1][2][3][4][5] our attention was turned to a subject, not yet investigated, namely proton (Z) and neutron (N) evenodd effects in prompt emission in fission. We have studied even-Z nuclei fissioning spontaneously or induced by thermal neutrons, like 233,235 U(n,f), 234 U(n,f), 239 Pu(n th ,f), 236,238,240,242,244 Pu(SF), 252 Cf(SF), because the extensive studies (e.g., [6][7][8][9]) regarding the Z even-odd effect in fragment distributions showed that the effect is most pronounced for this type of nuclei.…”

“…Average quantities as a function of Z (q(Z)), of A (q(A)), of TKE (q(TKE)) and total average <q> are obtained by averaging the PbP matrices over the fragment distributions Y(A,Z,TKE) in different ways (details are given in Refs. [1,2,10] and references therein). These distributions are constructed as Y(A,Z,TKE) = Y(A,TKE) p(Z,A) in which Y(A,TKE) are experimental distributions (usually reconstructed from the single ones Y(A), TKE(A) and σ TKE (A)) and the isobaric charge a e-mail: giubega georgiana@yahoo.com distributions p(Z,A) are provided by the Zp model of Wahl [11][12][13].…”

“…We started to study the basic features of the even-odd effect in prompt emission quantities, e.g., the behaviour of different average quantities like q(Z), q(A) of even-Z and odd-Z fragmentations, the behaviour of the global Z evenodd effect in different total average quantities, defined as [1,2]:…”

Abstract. The investigation of the proton even-odd effects in prompt emission in fission for even-Z actinides revealed basic features of the global even-odd effect in prompt emission similar with those in fission fragment yields and some particular aspects, such as: (1) the even-odd effects in prompt emission are the result of two contributions: a dominant intrinsic even-odd effect due to the even-odd nuclear character of fragments reflected in their properties and a weak even-odd effect caused by the fragment distributions (over which the multi-parametric matrices are averaged); (2) oscillations with a periodicity of about 5 mass units are present in different prompt emission quantities corresponding to even-Z and odd-Z fragmentations independent on the size of the even-odd effect in the charge yield Y(Z). These oscillations are due to the periodicity of nuclear properties of fragments; (3) a local even-odd effect in prompt emission quantities has been recently investigated. Similarities between prompt emission quantities and fragment yields were found in the case of the local even-odd effect, too. The local even-odd effect in both fragment charge yields and prompt emission quantities exhibit a pronounced increase at asymmetry values corresponding to fragmentations in which the heavy fragment (Z = 50 and/or N = 82) or the light one (Z = 28) is magic.
