Mo92,94,97,98(t,p) reactions atEt=17MeV

A systematic study of the molybdenum isotopes has been carried out by using the ($t$,$p$) reaction with a 17-MeV incident triton beam. Energy levels up to excitation energies of 5.1, 4.7, 2.1, and 3.8 MeV in the isotopes $A=94, 96, 99, \mathrm{and} 100$, respectively, were studied, and numerous spin assignments were made. Of particular interest is the trend of ground state and excited $0^{+}$ state transition strengths, which suggest a rapidly changing structure of the molybdenum ground states as a function of neutron number. The interacting boson approximation model is able to reproduce these trends only with the introduction of configuration mixing.
