Abstract

The half-lives of Al26m, Cl34, Co54 and Cu58 have been measured with an accuracy of about 12%. The activities were produced using (p,n) reactions on Mg26, S34, Fe54 and Ni58, respectively, at bombarding energies close to the reaction threshold. A beam chopping technique permitted a series of short irradiations of about one half-life interspersed with periods of several half-lives during which the activities were counted.

The values of the half-lives obtained were 6.374±0.016 sec for Al26m, if1.565±0.007 sec for Cl34, 0.1937±0.0010 sec for Co54 and 3.204±0.007 sec for Cu58.

    Citation Excerpt :

    Production of 26Al and that of its daughter isotope 26Mg via the Mg–Al reaction chain [more precisely via 25Mg(p,γ)26Al(β+)26Mg] occurs during H-burning (Arnould et al., 1999; Mowlavi and Meynet, 2000; Karakas and Lattanzio, 2003). 26Al produced during H-burning is present in two states, the ground state (∼80%; Iliadis et al., 2010) and an isomeric state (∼20%), with different half-lifes (705,000 years and 6.37 s, respectively (Freeman et al., 1965; Norris et al., 1983). Thus, the actual increase in the surface abundance of 26Al and 26Mg does not only depend on the rate of proton capture on 25Mg but also on the rate of proton capture on 26Al [26Al(p,γ)27Si(β+)27Al] and 26Mg [26Mg(p,γ)27Al] in the H-burning shell as well as on the efficiency of material transport from the site of previous H-burning to the stellar surface during dredge up events.
