A study of the121,123Sb(p, d) reactions

Levels of120,122Sb have been observed using the121,123Sb(p, d) reactions atEp= 26.2 MeV. Thirty-two levels of120Sb and thirty-four levels of122Sb are observed below 2.0 MeV excitation with an energy resolution better than 25 keV FWHM. Experimental angular distributions were compared to DWBA calculations in order to extractl-transfers and spectroscopic factors. Strong mixing between the 3s1/2, 2d3/2, 2d5/2, and 1g7/2 neutron orbitals is observed in both nuclei. Nuclear Reactions:121,123Sb(p, d),E=26.2 MeV; measuredσ(Ed,θ).120,122Sb deduced levels,l,J,π, spectroscopic factors. Enriched targets, magnetic spectrometer.

Low-lying excited states of106Ag studied with the103Rh (α,nγ)106Ag and104Pd (α,pnγ)106Ag Reactions

The level scheme of106Ag has been studied using the103Rh(α,nγ)106Ag and104Pd(α,pnγ)106Ag Reactions. The experimental information is taken fromγ-ray coincidence data using Ge(Li)-Ge(Li) and HPGe-planar Ge(Li) configurations andγ-ray angular distributions. With these measurements 126 γ rays have been assigned to106Ag with 116 deexciting 78 states below 2.26 MeV in excitation. The location of the 8.4-day 6+ isomer is established at 89.63±0.09 keV. Many of the low-lying states are interpreted in terms of a slightly deformed rotor model.

A Study of the120Sn(p, nγ)120Sb reaction

Levels of120Sb have been observed using the120Sn(p, nγ) reaction at proton energies between 3.90 and 6.25 MeV. Sixteen previously unobserved levels below 1.03 MeV were populated. The resulting level scheme is compared with that obtained using the121Sb(p, d) reaction.
