Description

There is renewed interest in the exploration of the nature of low-lying collective excitations in nuclei since several studies have posed serious questions regarding the veracity of multiphonon quadrupole vibrations. A recent survey of nuclei with low-lying states previously believed as having spherical vibrational structure found that very few passed the criteria. Of the few remaining candidates, which included $^{98,100}$Ru, the state of the spectroscopic data were insufficient to make conclusions. To address this issue, we have pursued a variety of studies to explore their nuclear structure, including a study on the $^{100}$Ru nucleus through a proton-transfer-reaction experiment at the Maier Leibnitz Laboratorium (MLL) facility in Garching, Germany. Using a 22 MeV proton beam, we performed the $^{103}$Rh($p,\alpha)^{100}$Ru reaction and the resulting emitted $\alpha$ particles were analyzed with a Q3D magnetic spectrograph. The results of the experiment, including the angular distributions of the population cross section, will be presented.
