Structure ofSb116Studied with theSn

Abstract

The '"Sn('He, d)" Sb reaction was performed to obtain a more sensitive test of two quasiparticle calculations for " Sb. These calculations gave a good description of the excitation energies and partial halflives of the low lying states of " Sb. Good agreement between measured and calculated spectroscopic factors is found. The calculated low lying J = 0+ state (E, = 420 keV) which has not been observed so far should be strongly excited in this reaction. However, no indication is found for such a state below E"=1200 keV. NUCLEAR REACTIONS 5'~S n(3He, d}, E =28.4 Me&, measured e(e). Sb deduced levels, J',~, S, DWBA analysis, magnqtic spectrograph, enriched target.

Half-life andg-factor of the 11/2? isomeric states in115Sb and117Sb

“…Experimental spectroscopic factors measured by Ishimatsu [3], Kamerroans [2] and Conjeaud [1] at projectile energies of 28.2, 28.5 and 18 MeV are summarized in Table 3.…”

“…Spectroscopic factors, which have been measured in the (3He, d) one-proton-transfer reaction on several tin isotopes, give the proton strength in the odd-A antimony isotopes for the different nuclear states. Different values for the spectroscopic factor of the lowest 11/2-state in ~17Sb have been found by Conjeaud [1] and Kamermans [2] and by lshimatsu [3]. The spectroscopic factor measured by Conjeaud [1] has been used to show that quadrupole and octupole vibrations have to be taken into account for a correct description of the low-lying 11/2-states in the odd-A antimony isotopes [4,5].…”
