Nuclear 2$\gamma$ decay is a second-order electromagnetic interaction wherein two photons are simultaneously emitted during a nuclear de-excitation. This transition is uniquely sensitive to the electromagnetic polarizability of the nucleus and has been studied in non-competitive cases for $0_2^+ \longrightarrow 0_1^+$ transitions between the first excited and ground states of even-even nuclei....

493. Measurements of polarization power of TUCANs UCN SCM polarizer and prototype spin analyzer

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

The TUCAN collaboration is developing a new source of Ultracold neutrons (UCN) that will be used in a neutron Electric Dipole Moment (nEDM) experiment, with a goal sensitivity of 10^(-27) e*cm which is 10 times more precise than the best measurement to date. UCNs are neutrons with energies below 300 neV, that are travelling with speeds less than 30 km/h. In order to carry out a world-leading...

432. (G*) The characterization of a spatially resolved multi-element laser ablation ion source

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

We report on the development of a multi-element ion source for calibration of a multi-reflection time of flight mass spectrometer. A laser ablation ion source (LAS) has been developed that can deliver specific, diverse species of ions from multi-element targets. It has been demonstrated that different target materials may be selectively ablated with a spatial resolution lower than 100𝜇m. Ion...

166. Search for the high-spin members of the $\alpha$:2n:$\alpha$ band in $^{10}$Be

Oral (Non-Student) / Orale (non-étudiant(e))

There is strong evidence that some states in $^{10}$Be exhibit a molecular-like $\alpha$:2n:$\alpha$ configuration. Based on theoretical studies, it appears that the $6.179$ MeV 0$^{+}$ state in $^{10}$Be has a pronounced $\alpha$:2n:$\alpha$ configuration with an $\alpha$-$\alpha$ inter-distance of $3.55$ fm [Itagaki and Okabe, (2000)]. This is 1.8 times more than the corresponding value for...
