91. TAGS and beta shape measurements for nuclear structure and reactor applications

Alejandro Algora (IFIC (CSIC-Univ. of Valencia))

Invited speakers

Nuclear structure and practical applications require beta decay data free from the Pandemonium effect [1,2]. For a proper beta decay description, we need information on the Q value of the decay, the half-life and the beta decay probabilities to the different levels in the daughter nucleus. Pandemonium, in this context, means that the beta decay probabilities might be distorted because of the...

107. Beta-decay spectroscopy with laser-polarized beams at CERN ISOLDE

Contributed Talks

Nuclear spin orientation provides access to an additional observable in beta-decay experiments – the anisotropy of radiation emission, which reflects the parity-nonconserving nature of the weak interaction [1]. The resulting directional distribution of the radiation depends on the asymmetry parameter, which is sensitive to the angular momentum change, as well as on the polarization of the...

104. Exploring the structure of nuclei with A≈100 via β decay

Desislava Kalaydjieva (University of Guelph)

2026-07-27, 4:50 p.m.

Contributed Talks

A sudden ground-state shape transition is known to occur sharply at $N=60$ for several nuclei in the $A\approx\!100$ region [1]. Dramatic changes are observed in the energy spectra of Sr and Zr, including an appearance of low-energy $0^+$ states that are associated to competing configurations characterized by different nuclear shapes. In contrast, in Mo isotopes the ground state shape...

27. Nuclear structure of $^{114}$Sn via $\beta$ decay of $^{114}$Sb with GRIFFIN

Madhu Madhu (Simon Fraser University)

Contributed Talks

The semi-magic Sn ($Z$ = 50) isotopes with neutron numbers extending from $N$ = 50 to beyond the $N$ = 82 shell, provide an important testing ground for studying the evolution of nucleon–nucleon interactions across the chain. Although ground states of Sn isotopes are predominantly spherical, mid-shell isotopes ($A$ = 112–122) display shape coexistence associated with proton 2p–2h intruder...
