Absolute gamma intensities in the A = 98 transitional nuclei and shape coexistence in /sup 98/Y

Journal Article · · Phys. Rev. C; (United States)
Absolute gamma intensities have been measured for the strong transitions in the decay chain /sup 98/Rb..-->.. /sup 98/Sr..-->.. /sup 98/Y..-->.. /sup 98/Zr and /sup 98/Nb..-->.. /sup 98/Mo and found approximately four times higher than those currently adopted. As a consequence, several contradictions in this crucial chain of nuclei are resolved. Shape coexistence is established in /sup 98/Y with a J/sup ..pi../ = 1/sup -/ ''spherical'' ground state and with a previously reported deformed band with band head at 495.7 keV.
