Nuclear alignment following compound nucleus reactions

Nuclear magnetic and quadrupole moments for nuclear structure research on exotic nuclei

“…• Isomers produced in a fusion-evaporation reaction [74,137] are highly spin-oriented. It has been shown that for all (heavy ion, xn) and (alfa, xn) reactions, the spin-alignment of the isomers can be described by a Gaussian distribution function…”

“…The B 2,4,6 coefficients contain the alignment of the initial state, which was considered to be a Gaussian distribution centred about M=0 and parametrised as [36]:…”

“…The data were fitted using the STAG code which follows the method outlined in Ref. [36]. The 2741 keV transition decays from the ground state and was used to evaluate the parameter σ, used in the alignment distribution described by Eq.…”
