AbstractAbstract
[en] l-forbidden M1 transitions of the (2dsub(3/2) → 3Ssub(1/2)) type in barium nuclei are investigated. Life times of the first excited states of 131Ba with 108.2 keV energy (Tsub(1/2)=0.35+-0.05 ns) and 133Ba with 12.3 keV energy (Tsub(1/2)=6.8 +- 0.4 ns) have been measured by the delayed coincidences method. Experimental probabilities of γ-transitions in Ba nuclei being considered and the one-particle Moshkovski bremsstrahlung factors have been given. The comparison of the one-particle bremsstrahlung factors for the 108.2 and 12.3 keV transitions with the systematics of the similar transitions in another odd-neutron nuclei resulted in revealing the trend of increasing the bremsstrahlung factors with approaching the number of nucleons in a nucleus to closed nucleon shells with Z=50 and N=82
