Quasi-Moessbauer effect in two dimensions
Expressions for the absorption spectrum of a nucleus in a three- and a
two-dimensional crystal respectively are obtained analytically at zero and at
finite temperature respectively. It is found that for finite temperature in two
dimensions the Moessbauer effect vanishes but is replaced by what we call a
Quasi-Moessbauer effect. Possibilities to identify two-dimensional elastic
behavior are discussed.Comment: 18 pages, 5 figures, notation simplifie
