Description

In this report, we focus on 22Si, likely the lightest bound nucleus with Tz=−3, using Nuclear Lattice Effective Field Theory (NLEFT) with chiral forces. Our calculations agree with existing data and predict it as a proton-dripline nucleus, along with its 2+ state, radius, and spatial properties. Using nucleon ordering operators, we reveal nucleon spatial arrangement and localization, linked to shell closure features. Moreover, we introduce a novel pinhole method bridging NLEFT and shell model, offering new perspectives into a more comprehensive understanding of nuclear structure.
