Probing exotic cross-shell interactions at $N=28$ with single-neutron transfer on $^{47}$K
Probing exotic cross-shell interactions at $N=28$ with single-neutron transfer on $^{47}$K
We present the first measurement of the $^{47}$K($d,p\gamma$)$^{48}$K transfer reaction, performed in inverse kinematics using a reaccelerated beam of $^{47}$K. The level scheme of $^{48}$K has been greatly extended with nine new bound excited states identified and spectroscopic factors deduced. Detailed comparisons with SDPF-U and SDPF-MU shell-model calculations reveal a …
