Tidal wave in 102Pd: Rotating condensate of up to seven d-bosons

TL;DR

This paper interprets the yrast states of certain nuclei as a rotating condensate of d-bosons, supported by experimental evidence and theoretical models, revealing anharmonic effects due to boson interactions.

Contribution

It introduces a novel interpretation of nuclear yrast states as a rotating condensate of up to seven d-bosons, combining experimental findings with theoretical models.

Findings

Experimental evidence of anharmonicity in nuclear states.

Validation of the rotating condensate model through calculations.

Identification of a tidal wave phenomenon in 102Pd.

Abstract

The yrast states of even even vibrational and transitional nuclei are inter- preted as a rotating condensate of interacting d-bosons and the corresponding semi-classical tidal wave concept. A simple experimental manifestation of the anharmonicity caused by the boson interaction is found. The interpretation is substantiated by calculations based on the Collective Model and the Cranking Model.
