Spin-dependent interactions play essential roles in nuclear structure and reactions. One of the best known examples is the spin asymmetry found in nucleon elastic scattering, which is a direct manifestation of the spin-orbit interaction. Since the spin-orbit interaction is expected to work in the surface region, it is natural to expect that such interaction could be strongly modified by the...
Observation of high 2$^{+}$ excitation energy in $^{68}$Ni (Z = 28, N = 40) had drawn a clear signature of double magic character in this nucleus [1]. And while $^{68}$Ni can be described as spherical isotope, 2$^{+}$ excitation energy of $^{66}$Fe drops significantly [2], indicating deformed shape of $^{66}$Fe. $^{67}$Co isotope is in between $^{68}$Ni and $^{66}$Fe nuclei and found to share...
The level structure of neutron rich $^{93,94,95}$Sr were studied via the \dtsr{94,95,96}, one neutron pickup reactions at TRIUMF. Excited states were populated when $^{94,95,96}$Sr beams of 5.5 AMeV bombarded a 0.5 mg/cm$^2$ CD$_2$ target. The de-exciting $\gamma$-rays and outgoing charged particles were detected by using the TIGRESS and SHARC arrays, respectively. The level scheme was...
The atomic nuclei have dual features, the single-particle shell nature and collective modes, which are competing with each other to express the actual nuclear structure. Here we demonstrate the precision analysis of this competition by focusing on the magnetic moment of an isomeric state of a neutron-rich nucleus 75Cu, where an intriguing shell evolution has been reported.
The experimental...
