摘要: A hypothesis of the chiral symmetry breaking opened a new opportunity for study spontaneous time-reversal in an atomic nucleus. The occurence chirality has been found 126,128Cs nuclei which specific electromagnetic selection rules have Doppler Shift Attenuation experiments. Here, recent DSA measurements 124Cs nucleus are presented. was produced 114Cd(14N,4n)124Cs reaction at Heavy Ion Laboratory University Warsaw. obtained results agree with basic expectations deduced from breaking. connection between phenomenon and is discussed possibility using doublets studies fundamental time reversal suggested.
