Abstract: The j − 1 anomaly is associated with the atypical ordering of the 7 / 2 + and 9 / 2 + states, arising from the π g 9 / 2 − 3 multiplet. According to the shell model, M 1 transitions between the states of the same- j multiplet are forbidden. Yet, such transitions are observed in odd-A Ag nuclei. Therefore, it is of upmost interest to study M 1 transitions strengths. However, the only silver nucleus, where lifetime data exists to date is 101 Ag, but this nucleus does not exhibit the anomalous trend, observed in the heavier Ag nuclei. Indeed, the lightest Ag nucleus, where the j − 1 anomaly occurs is 103 Ag. Therefore, 103 Ag is in the focus of the present article, where new lifetime data is acquired via RDDS measurements. Reduced electromagnetic transition probabilities are evaluated and compared to Empiric and Large-Scale Shell-Model calculations.
