Coulomb Displacement Energies Between Analog Levels for 3 ≤a≤ 239

“…1 having the same isobaric The present compilation lists experimental Coulomb spin T yielded the following equations: displacement energies DE C for some 2300 pairs of corresponding levels, or about 40% more than the combined total DE C Å 1348.5(1)ZU /A 1/3 0 644.9(2), for T Å 1/2, of the earlier works for A Å 1-45 [1] and A Å 44-239 [2].…”

“…[2]. Excitation energies in columns five and DE C Å 1411.1(3)ZU /A 1/3 0 886.8(13), for T Å 3/2, seven of the Table are given as found in the literature, in DE C Å 1406.7(6)ZU /A 1/3 0 872.8(32), for T Å 2. some cases to a fraction of an eV, or when applicable were calculated with recent proton separation energies [3].…”

“…Most of the feedback we have had from our earlier tables [1,2] grew out of searches for nuclei far from the…”

“…The item that experimenters most often needed was an accurate guide to DE C in order to estimate where M Zú is the mass of the higher Z (''Z greater'') member the mass and stability of new species. The (sometimes conof an analog pair and M Zõ is the mass of the lower Z (''Z siderably) reduced uncertainties as compared to the earlier lesser'') member, and D nH is the neutron-hydrogen mass tables [1,2], the use of more recent masses [3], and the difference of 782.354(3) keV [3]. Mass differences between parameterization of DE C for different values of T should all ground states are calculated using the most recent mass table constitute steps in this direction.…”

T=13 double isobaric analog state inCe138via pion-induced double charge exchange

“…In a simple model, the Q value to the DIAS is given by QDws =~Ec,i+~Ec, 2 2~nI» where 5" is the neutron-proton mass difference and DEC & and AE& 2 are the Coulomb displacement energies for the isobaric analog state and the DIAS. For EEc, we use 14.728 MeV, the average Coulomb displacement energy for ' La [18]. For AEc2 we use 14.859 MeV, obtained from the value for ' Ce [18] (14.800 MeV) increased by 59 keV to allow for the change in mass to Ce.…”
