  1. 7. Projectile Breakup of $^7$Be on $^{12}$C at 5 MeV/u

    Breakup reactions involving loosely bound stable nuclei with prominent cluster structures like $^{6,7}$Li have been widely studied [1-3]. Similar studies on radioactive nuclei are comparatively lesser in number due to issues of availability and beam intensities. Reaction studies of the $^7$Be nucleus on $^{12}$C target reported very few coincidence events from breakup [4]. Similar results were...

  2. 6. Investigating the deformation of the intruder isomeric 1/2+ state in 79Zn (N=49) via Coulomb excitation

    For nuclei with $N$ around 50, several pieces of evidence supporting shape coexistence close to $^{78}$Ni have been found. In particular, the ∼940-keV 1/2$^{+}$ isomeric state in $^{79}$Zn has been interpreted as an intruder state, related to neutron excitations across N=50. Laser-spectroscopy measurements found a large isomeric shift for this state with respect to the $^{79}$Zn 9/2$^{+}$...

  3. 53. Measurement of the quadrupole moment of the first 2⁺ state in 110Sn

    Submitted oral (In person)

    The quadrupole moment of the 2+1 ​ state in 110Sn has been determined, along with a more precise determination of the reduced transition probability B(E2;2+1 ​-> 0+1​). The measurement results were obtained through a safe Coulomb excitation experiment at HIE-ISOLDE, using the Miniball setup. Preliminary results yield...

  4. 58. Evolution of the one-phonon mixed-symmetry 2+ state in the N=80 isotones

    Submitted oral (In person)

    The formation of nuclear quadrupole collectivity and the contributions of valence protons and neutrons to it is a vivid research field in contemporary nuclear structure physics, including activities at the ISOLDE facility. The excited proton and neutron configurations can couple to predominantly isoscalar and isovector excitations of the nuclear valence shell. The latter are addressed as...

  5. 59. Complementary measurements of octupole collectivity in 146Ce
    Ben Rhys Jones (University of Liverpool (GB))
    28/11/2024, 10:00
    Submitted oral (In person)

    I intend to present the preliminary results from the IS708 experiment, which plans to use both ISS and Miniball to study octupole collectivity in $^{146}$Ce using the complementary techniques of inelastic scattering and Coulomb excitation, respectively. The ISS experiment will use the Liverpool silicon array to measure the excited 2+ and 3- states populated in a (d,d’) reaction. The solenoidal...

  6. 20. Detailed studies of $^{214,216,218}$Po via $\beta$ decay of $^{214,216,218}$Bi

    The odd-odd bismuth isotopes ($Z$ = 83) and their $\beta$-decay polonium daughters $(Z\,=\,84)$ are excellent subjects for nuclear structure studies. With only one and two protons, respectively, above the closed shell $Z$ = 82, they provide an outstanding testing ground for shell-model calculations, and in the case of polonium isotopes, also for the seniority scheme. Moreover, both isotopic...
