In-beam γ -ray spectroscopy of low- and medium-spin levels in Po211

J. M. K. Slotte, P. Granholm, R. Öhman, T. Lönnroth et autres

The structure of the low- and medium-spin levels of the $^{211}\mathrm{Po}$ nucleus have been studied with in-beam $\ensuremath{\gamma}$-ray spectroscopy with the $^{208}\mathrm{Pb}(\ensuremath{\alpha},n)^{211}\mathrm{Po}$ fusion-evaporation reaction. The level scheme was further extended with levels of the configurations $\ensuremath{\pi}{({h}_{9/2})}_{{2}^{+}\ensuremath{-}{4}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{g}_{9/2}$, $\ensuremath{\pi}{({h}_{9/2})}_{{8}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{g}_{9/2}$, $\ensuremath{\pi}{({h}_{9/2})}_{{2}^{+}\ensuremath{-}{4}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{i}_{11/2}$, $\ensuremath{\pi}{({h}_{9/2})}_{{2}^{+}\ensuremath{-}{4}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{j}_{15/2}$, $\ensuremath{\pi}{({h}_{9/2}{f}_{7/2})}_{{8}^{+}}\ensuremath{\bigotimes}\ensuremath{\nu}{g}_{9/2}$, and $\ensuremath{\pi}{({h}_{9/2})}_{{0}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{({g}_{9/2})}_{{0}^{+}}^{2}{({s}_{1/2})}^{\ensuremath{-}1}$. …

Detailed spectroscopy of Bi195

A. Herzáň, S. Juutinen, Kalle Auranen, T. Grahn et autres

An experiment focused on the study of shape coexistence and new high-spin structures in $^{195}\mathrm{Bi}$ has been performed. The nucleus is in a transitional region of the bismuth isotope chain. A large number of new states have been found, resulting in a …

Decay of quasimolecular states in 26Mg

S. Yu. Torilov, N. A. Maltsev, Vladilen Z. Goldberg, Konstantin A. Gridnev et autres

A resonance-like structure in the excitation function for elastic and inelastic 14 C + 12 C interactions is investigated. Angular distributions for the 14 C( 12 C, 10 Be) 16 O reaction at center-of-mass energies of 21.1, 23.5, and 24.6 MeV are …

Quasimolecular states in a reaction with carbon isotopes

S. Yu. Torilov, N. A. Maltsev, Vladilen Z. Goldberg, Konstantin A. Gridnev et autres

The angular distribution of the products of the 14C + 12C reaction at the energies E cm = 22.1, 23.5, and 24.6 MeV has been studied near a 23.5-MeV quasimolecular resonance. Channels with the yield of 8,9,10Be have been considered for various …

Quasielastic backscattering and barrier distributions for the 6 , 7 Li + 64 Zn systems

Mile Zadro, Pierpaolo Figuera, Alessia Di Pietro, M. Fisichella et autres

Excitation functions of quasielastic scattering at backward angles were measured for the weakly bound ${}^{6}$Li and ${}^{7}$Li projectiles on a ${}^{64}$Zn target at energies around the Coulomb barrier. The corresponding barrier distributions were derived from the experimental cross sections. The experimental data …

Nuclear level density and γ -ray strength function of 43 Sc

A. Bürger, A. C. Larsen, S. Hilaire, M. Guttormsen et autres

The nuclear level density and the $\ensuremath{\gamma}$-ray strength function have been determined for ${}^{43}\mathrm{Sc}$ in the energy range up to 2 MeV below the neutron separation energy using the Oslo method with the $46\mathrm{Ti}$$(p,\ensuremath{\alpha})$${}^{43}\mathrm{Sc}$ reaction. A comparison to ${}^{45}\mathrm{Sc}$ shows that the …

Primary γ -ray spectra in 44 Ti of astrophysical interest

A. C. Larsen, S. Goriely, Arnold Burger, M. Guttormsen et autres

Primary $\ensuremath{\gamma}$-ray spectra for a wide excitation-energy range have been extracted for ${}^{44}$Ti from particle-$\ensuremath{\gamma}$ coincidence data of the ${}^{46}$Ti($p,t\ensuremath{\gamma}$)${}^{44}$Ti reaction. These spectra reveal information on the $\ensuremath{\gamma}$-decay pattern of the nucleus and may be used to extract the level density and …

Do light nuclei display a universalγ-ray strength function?

M. Guttormsen, A. C. Larsen, Arnold Burger, A. Görgen et autres

In this work we focus on properties in the quasi-continuum of light nuclei. Generally, both level density and γ-ray strength function (γ-SF) differ from nucleus to nucleus. In order to investigate this closer, we have performed particle-γ coincidences using the reactions (p, …
