Fine structure of the pygmy quadrupole resonance in $^{112, 114}$ Sn isotopes

N. Tsoneva, M. Spieker, H. Lenske +1

The electric quadrupole response in $^{112, 114}$ Sn isotopes is investigated by energy-density functional (EDF) and three-phonon quasiparticle-phonon model (QPM) theory with special…

High-resolution $(p, t)$ study of low-spin states in $^{240}$ Pu: Octupole excitations, $α$ clustering, and other structure features

M. Spieker, S. Pascu, D. Bucurescu +6

A high-resolution $(p, t)$ experiment at $E_{p}$ = 24 MeV was performed to populate low-spin states in the actinide nucleus $^{240}$ Pu. The Q3D magnetic spectrograph of the Maier-L…
