Rare Earth Nucleus

The low-energy two-quasiparticle bandhead energies for the odd-odd Z=101 nucleus 250 Md are evaluated using a zero range residual neutron-proton interaction. The 250Md ground state is seen to have the spin-parity Iπ=0- corresponding to the singlet band from the configuration {p : 7/2[514]⊗n:7/2[624]} in violation of the Gallagher-Moszkowski (GM) coupling rule. The situation here is shown to be almost identical to that for the rare-earth nucleus 166 Ho , which is the only well-established exception to the GM rule known so far. Analysis of the expected low energy spectrum, including the rotational levels, for 250 Md reveals the occurrence of an as-yet-unobserved long-lived high-spin Iπ = 7- isomeric state around (80±30) keV with dominant ε and α decay modes.

The absorption spectrum of gaseous aluminium monofluoride has been examined in the region 1250 to 2000 Ǻ. Six new singlet band-systems have been found. Four of the excited states have also been observed in emission in transitions to the lowest excited singlet state A 1 п, at longer wave-lengths. The energies and products of dissociation of some of the states are considered.
