Abstract
The quadrupole moments of the neutron isomers in140,142Sm were determined by measuring the quadrupole interaction of Sm in Gd using single crystals. The moment for the 10+ isomer in140Sm was determined to be ¦Q¦=167(48) fm2 and for the 7− isomer in142Sm ¦Q¦=112(27) fm2. The quadrupole moments are a measure for a deformation which turned out to be very similar to the deformation found for corresponding proton isomers in Gd isotones.

A time integral measurement was already performed by [18], but inconsistent results for the ratio of152Sm to152Sm prompted us to study the interaction time differentially
