Description

Lifetime measurements are commonly used to unravel the nature and properties of nuclear states, as they are closely related to transition probabilities, which provide information on the nuclear wave functions. The aim of the experiment here presented was to study the interplay of spherical (0 ℏω) and intruder (2 ℏω) configurations in the low-lying states of isotopes on the edge of the N=20 island of inversion. Specifically, the goal was to determine the lifetime of the first two 2+ states of $^{34}$Si and the first $5/2^+$ state of $^{35}$P using the Doppler Shift Attenuation Method. The experiment was conducted at the LNL facility in November 2022, employing the PRISMA magnetic spectrometer and the AGATA array.

This presentation offers an overview of the current status of data analysis. The data sorting has been concluded, with our main focus now on further developing the GEANT4 simulation to mimic the experimental conditions. The simulation is necessary for extracting lifetimes from the experimental line shapes.
