Single-particle and collective excitations in $^{62}$ Ni

M. Albers, S. Zhu, A. D. Ayangeakaa +21

{\bf Background:} Level sequences of rotational character have been observed in several nuclei in the $A = 60$ mass region. The importance of the deformation-driving $π f_{7/2}$ and $…

Study of the astrophysically important $^{23} Na (α, p)^{26} Mg$ and $^{23} Na (α, n)^{26} Al$ reactions

M. L. Avila, K. E. Rehm, S. Almaraz-Calderon +11

The $^{23}$ Na $(α, p)^{26}$ Mg and $^{23}$ Na $(α, n)^{26}$ Al reactions are important for our understanding of the $^{26}$ Al abundance in massive stars. The aim of this work is to report…

Study of $(α, p)$ and $(α, n)$ reactions with a Multi-Sampling Ionization Chamber

M. L. Avila, K. E. Rehm, S. Almaraz-Calderon +11

A large number of $(α, p)$ and $(α, n)$ reactions are known to play a fundamental role in nuclear astrophysics. This work presents a novel technique to study these reactions with the…

Longitudinal Wobbling in $^{133}$ La

S. Biswas, R. Palit, S. Frauendorf +13

Excited states of $^{133}$ La have been investigated to search for the wobbling excitation mode in the low-spin regime. Wobbling bands with $n_{ω}$ = 0 and 1 are identified along with…

In-beam spectroscopy of medium- and high-spin states in $^{133}$ Ce

A. D. Ayangeakaa, U. Garg, C. M. Petrache +14

Medium and high-spin states in $^{133}$ Ce were investigated using the $^{116}$ Cd( $^{22}$ Ne, $5 n$ ) reaction and the Gammasphere array. The level scheme was extended up to an excitat…

Shape coexistence and the role of axial asymmetry in $^{72}$ Ge

A. D. Ayangeakaa, R. V. F. Janssens, C. Y. Wu +22

The quadrupole collectivity of low-lying states and the anomalous behavior of the $0_{2}^{+}$ and $2_{3}^{+}$ levels in $^{72}$ Ge are investigated via projectile multi-step Coulomb excitat…

Direct Evidence of Octupole Deformation in Neutron-Rich $^{144}$ Ba

B. Bucher, S. Zhu, C. Y. Wu +31

The neutron-rich nucleus $^{144}$ Ba ( $t_{1/2}$ =11.5 s) is expected to exhibit some of the strongest octupole correlations among nuclei with mass numbers $A$ less than 200. Until no…

Independent measurement of the Hoyle state $β$ feeding from 12B using Gammasphere

M. Munch, M. Alcorta, H. O. U. Fynbo +28

Using an array of high-purity Compton-suppressed germanium detectors, we performed an independent measurement of the $β$ -decay branching ratio from $^{12} B$ to the second-…
