Query: Isospin composition of the high-momentum fluctuations in nuclei from
  asymptotic momentum distributions   The variations of short-range correlations (SRC) across nuclei can be
quantified in an approximately model-independent fashion in terms of the
so-called SRC scaling factors. We provide predictions for the SRC scaling
factors for both bound protons and bound neutrons across the nuclear periodic
table and determine the contribution of the different nucleon pair combinations
to this quantity. Thereby we employ the low-order correlation operator
approximation (LCA) to compute the SRC contribution to the single-nucleon
momentum distribution. We do this for a sample of fifteen nuclei from He to Pb
thereby gaining access to the evolution of the SRC scaling factor with the
nuclear mass and the neutron-to-proton ratio. For the studied sample of fifteen
nuclei, the total SRC scaling factor is in the range 4.05-5.14. The computed
SRC scaling factors in the LCA are in line with those of ab-initio calculations
and with measured quantities from SRC-sensitive inclusive electron-scattering
data. In asymmetric nuclei there are sizeable differences between the SRC
scaling factors for protons and neutrons. It is suggested that this phenomenon
may impact the variations of the magnitude of the European muon collaboration
(EMC) effect across nuclei. Our results corroborate the finding that SRC
physics can be qualitatively understood by universal principles that build on
local modifications of mean-field wave functions of nucleon pairs.
