The decay modes of proton drip-line nuclei with A between 42 and 47

Abstract

If we analyse the semantic field of the term “anthropology” we find that the idea covers a very wide range. At the same time however, expressed opinion follows three basic ways. First of all through definitions or lists of characteristics. Or else through the choice of methods used to analyse the human fact. Finally there are the moments where a researcher admits that he can define only the contours of a concept whose core he still ignores. We can say that there exists an “anthropology” in an ethnographic sense or a “biological anthropology”. But every thought also has an “anthropological instant”, that is an explicit or implicit representation of humanity which stands out from interpretations and epistemological passages

“…In most cases agreement was found, but in some instances we had to adjust masses. These are discussed in the following: Borrel et al (1992) with the reported observation of this isotope by Rykaczewski et al (1995). Evidence for 103 Sb was also reported by Smith et al (2006), who find a significant β-branch.…”

Spectroscopic studies of the βp and β2p decay of 23Si

“…As mentioned in the introduction, after the observation of this decay mode for 22 [7], and 43 Cr [8], the identification of a β-delayed twoproton branch for 23 Si closes the list of known β2p emitters for T z = −5/2 nuclei: All nuclei of this series which have been studied experimentally, from the lightest one ( 23 Si) to the heaviest one ( 43 Cr), exhibit this decay mode. Theoretically this mode is expected to exist for all T z = −5/2 nuclei which are bound or sufficiently bound by the Coulomb barrier to decay by β decay.…”

“…However, for some nuclei at the drip line, even more exotic decay branches are possible. After the first observation of β-delayed two-proton emission for 22 Al [2], 6 more β2p emitters have been found: 26 P [3], 35 Ca [4], 31 Ar [5], 27 S [6], 39 Ti [7], and 43 Cr [8]. For 31 Ar, a β-delayed three-proton emission has been reported [9a] D. Bazin et al.…”

Decay of proton-rich nuclei between 39Ti and 49Ni

“…For 39 Ti, the half-life and the main decay branches, including the β2p decay, have been observed previously [17,18]. Some information, like rough lifetime estimates and a few delayed proton lines, is also available for 43 Cr, 46 Mn and 46,47 Fe [19]. For the most exotic isotopes, 42 Cr, 45 Fe and 49 Ni, only their existence was reported [1].…”
