Number-projected three-quasiparticle description of the odd Sn isotopes

Abstract: An account is given of the description of the low-energy properties of the odd Sn nuclei in terms of number projected one-(1 q.p.) and three-quasiparticle (3 q.p.) states. The shell model space for the neutrons consists of one major shell. A simple Gaussian force is used as an effective interaction. Its strength and the single-particle energies, which are the only parameters, are derived in a consistent way from spectroscopic data on the onequasiparticle states. We find that the spectra can be well interpreted… Show more

“…In the three-quasiparticle description of the odd tin isotopes by van Gusteren et al [11] the g-factor was calculated as g~or = + 0.47 again in excellent agreement with our experimental result. This model calculation reproduces also the ground state magnetic moment exactly, whereas the calculated half-life of the 159 keV state theor T1/2 (159 keV)=2.1 ns is about one order of magnitude too long.…”

“…One reason for this is that here also particle-hole excitations of the closed shell were included, which makes the nucleus sufficiently soft to lower collective excitations of the vibrational type. Another point is however that in Sn nuclei (Z=50) more complicated collective states have been observed in even nuclei [26] which possibly also play a role in the odd nuclei [22]. In the present investigation we do not find indications for a similar situation around the N = 50 closed shell.…”

“…one-broken-pair model to the odd N=50 isotones are considerably more convincing than earlier applications to odd Sn isotones [21,22]. One reason for this is that here also particle-hole excitations of the closed shell were included, which makes the nucleus sufficiently soft to lower collective excitations of the vibrational type.…”
