Relation Between a Three Parameter Formula for Isotope Shifts and Staggering Parameters

TL;DR

This paper explores how a three-parameter formula can effectively describe the complex, rapidly changing staggering parameters observed in isotope shifts, offering a simplified explanation for even-odd effects.

Contribution

It demonstrates that a fixed-coefficient three-parameter formula can account for the behavior of staggering parameters in isotope shifts, simplifying previous descriptions.

Findings

The three-parameter formula explains rapid variations in staggering parameters.

Fixed coefficients in the formula can reproduce complex isotope shift behaviors.

The approach offers a unified explanation for even-odd effects in isotope shifts.

Abstract

It is noted that the staggering parameters used to describe even-odd effects for isotope shifts can in some cases exhibit very rapidly varying behavior as a function of neutron number. On the other hand a three parameter formula (3P) with fixed coefficients can explain the same behaviour.
