Nuclear spectroscopy in 48V via the 34S(16O,pn)48V reaction

The electromagnetic decays of 18 bound states in ⁴⁸V have been studied via the ³⁴S(¹⁶O, pn)⁴⁸V reaction, at incident ion energies of 30–36 MeV. At these energies pn, 2pn, 2p, αp, αn and 2n exit channels were open. Spins and parities of the levels as well as the branching and mixing ratios of their decay γ-rays have been obtained from angular distribution, excitation function, and high resolution γ-γ and n-γ coincidence measurements. Six, and possibly seven, members of a very pure rotational negative parity band have been identified. This band is based on a 1^? low-lying core excited state with probable configuration $\text{(π}\text{d}{}_{\mathrm{<mtext>3</mtext><mtext>2</mtext>}}\text{)}{}^{\mathrm{?1}}\text{(π}\text{f}{}_{\mathrm{<mtext>7</mtext><mtext>2</mtext>}}\text{)}{}^4\text{(ν}\text{f}{}_{\mathrm{<mtext>7</mtext><mtext>2</mtext>}}\text{)}{}^5$.
