The level structure of W-187 has been studied using prompt and delayed gamma-gamma coincidences from thermal neutron capture in W-186 and also measuring the (d, p) reaction. From these data and those of previous studies a total of 170 levels (121 connected by gamma transitions) have been established for energies below 2.35 MeV. Some of these levels have been grouped into rotational bands built on 14 intrinsic states of quasi-particle and quasi-particle plus phonon character. Of particular interest has been the identification of "quasi bands" with inverse spin sequence based on the newly established isomeric 11/2(+) state at 410.1 keV Although the DWBA analysis permitted definite spin-parity assignments for most states a large number of particle transitions have "anomalous" angular distribution shapes with respect to the DWBA which indicate an influence of strong mixing between particle and probably hole states.

Struktura energetických hladin W-187 byly studována pomocí rychlých a zpožděných gama -gama koincidencí ze záchytu termálního neutronu na W-186 a také měřením reakce (d,p).
