Lifetime measurements for the proposed antimagnetic rotational band in $^{101}$Pd

It has become well known by active researches in the last two decades that particle-hole combinations of dissimilar nucleons in high-$j$ orbitals can create novel structures such as magnetic rotation (MR) bands and antimagnetic rotation (AMR) bands around doubly magic nuclei. We proposed an antimagnetic rotational band including the $h_{11/2}$ neutron orbital in $^{101}$Pd based on the previous in-beam $\gamma$-ray spectroscopy by using the reaction $^{68}$Zn($^{37}$Cl,1p3n). However, we could not confirm the antimagnetic rotational character at that time for lack of lifetime data. Since a thick target was used in that experiment, it was possible to extract lifetimes for several levels in the ${\nu}h_{11/2}$ band through the analysis of Doppler broadened line shapes of $\gamma$-rays. The results of those analyses will be presented in this talk.
