“…Also the wave functions obtained from RPA calculations [2,4] reproduce the observed spectroscopic factor and the BMI transition probability within the experimental errors. Furthermore the numbers are also in fair agreement with results from recent (e,e') experiments [9].…”

“…Since the unper~urbe~ energies for proton an~ neutron configurations are almost equal (5.55 MeV and 5.86 MeV, respectively) they are expected to mix strongly. Exactly this is the result of the early RPA calculations of Gillet et al [2] and of TDA calculations of Vergados [3]. This did not change in more elaborate and sophisticated RPA calculations [4].…”

“…to be uneorrelated (vacuum), (ii) the 1 + state to consist of only lp-lh configurations and (iii) n ~m excitations with s = s and n > 2 to be negligible. All the differ ~ ent available model calculations [2,3,4] have shown that these assumptions are justified to a high degree. The wave function can then be written as: areas in fig.…”

The 1 state at 5.846_MaV in ph was --Z093 208 observed in a high-resolution Bi(d, He) ~ Pb experiment with a spectroscopic factor of C-S = 0.17. From this, together with the transition probability BMIf = 1.6g~ from a (~,y') experiment N and the normalization condition we derive size and relative phase of proton and neutron spinflip amplitudes of the i-state wave function; these are in good agreement with predictions of TDA and RPA calculations.Presumably only few nuclear states have ever been subject to so much interest from both theo~ retical ag~_experimental sides as the lowest 1 state in -~sPb [1]. The reasons are the expected simplicity of its configuration and that its energy and particle-hole structure allow one to expect information on the spin-dependent parts of the residual interaction. It is the aim of the present work to determine the leading terms of factor was determined relative to --Pb, where we observe filled 3Sl/^, ~ /2~ ih11/2 and 2d5/2 shells. We obtain a va~ue ,

Abstract. Energy spectrum and electromagnetic properties of 2~have been studied in the cluster-vibration model (CVM). The lifetime of 0.3 ms was predicted for the 2.3 keV level which is of significance for considerations of the 2~ solar neutrino detector. In order to obtain a more reliable estimate for the neutrino cross section on 2~ PACS:we have investigate here the structure of the daughter nucleus, 2~in the framework of the cluster-vibrational model (CVM) [3][4][5]. The best way to check the validity of our theoretical model for 2~ would be the comparison of the theoretical predictions for the half-life of the 2.3 keV state with the experiment.

“…In the exchange scattering the projectile is captured and transfers momentum p=ki-22 to the bound particle thereby expelling it from the target with momentum 21. Introducing the initial and final relative momentum k and k' of the two nucleons it follows that: q=k-k' (52) P 2= (k2+k,2)_q2…”
