Points to note for DDLZ1:
The rho-T and rho-VT terms are NOT employed in this DDLZ1: at least, I have not found.
[Page 4, left] About pseudo-spin symmetry, the U-218 nucleus is also included into their reference data, in order to eliminate the spurious shell closures.
[Table 1] There are 9 parameters a-d to be fitted, in addition to the usual m and g ones. There its saturation density is the result, not the fittable parameter.
[Page 4, right] Specifically, DD-LZ1 presents a larger saturation density than DD-ME2, PK1 and PKO1, close to PKA1.
[Page 4, right] About pseudo-spin symmetry, the merit of DDLZ1 is described: see also Ref. [37]. The scalar mass Ms* is emphasized as a key factor.
