Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 August 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

This research program, located at an undergraduate institution, features hands-on, table-top experiments using lasers and heated atomic samples to measure with great accuracy certain properties of complex atomic systems. These experimental results can then be compared to state-of-the-art models with which theoretical physicists can predict these same properties. With better understanding of the workings of these…
